# Heavy Gear

Heavy Gear is a mecha science fiction game universe published since 1994 by Canadian publisher Dream Pod 9. It includes a tabletop tactical wargame, a role-playing game, and a combat card game (Heavy Gear Fighter). The setting is also known through the PC game incarnations published by Activision in 1997 and 1999, which were developed after Activision lost the rights to the Battletech/MechWarrior series. It also spawned a 40-episode, 3D-animated TV series in 2001, which featured a much simplified version of the universe developed in the role-playing game.
The background universe of the game is very detailed – more than a hundred books and game accessories have been published since 1994. A continual epic storyline runs throughout all of the game's material, with new publications moving chronologically along the timeline. Heavy Gear is best known for its humanoid combat vehicles (or mecha) – the Gears and Striders used by the military forces in the setting.

## Publication history

The game designers at Dream Pod 9, at that time a division of Ianus Publications, decided after Gen Con 1993 that they wanted to design a game system they could use to publish their own books; this led to the Silhouette System which would be first used for Heavy Gear.

## Plot and setting

Heavy Gear is set on a distant, fictional planet called Terra Nova around 4,000 Earth Standard Years from now (AD 6132). Terra Nova was once the pride of the United Earth Government's colonies. However, an economic collapse forced the UEG to abandon Terra Nova and its other colonies centuries before the period depicted in the game setting, leaving Terra Nova in a Dark Age. Eventually, City-states rose from the ashes and either through treaties or tyranny, united to form national unions called Leagues. These Leagues would in turn ally (again either peacefully or forcibly) to form the superpower blocs that dominated the temperate southern and northern hemispheres of the planet.
The planet's geography is primarily land containing deep underground water reserves, but few large bodies of open water and no oceans. This is unlike Earth, which is covered by 70% ocean. The planet has its own existing ecosystem of plants and animals, such as the bison that Barnaby used as livestock, and the Hopper, which is the equivalent of Earth's rabbit, though most animals are reptilian in nature. The single dominant land feature is a massive mineral rich, hot desert belt around the equator of the world known as the Badlands. This territory is not dominated by any one political group, and is considered open territory to everyone, and contains many bandit groups known as Rovers. Most people live in the northern or southern polar regions where temperatures are more acceptable to human life, and other terrain types such as forests, grasslands, swamps, and jungles can be found. Small ice caps with arctic conditions and glaciers are found on the true north and true south poles.
As the setting is primarily the backdrop for a series of strategy, roleplaying, and video games the military and weaponry are the main focus. One of the most popular weapon systems of the various groups on Terra Nova are the machines known as Heavy Gears that give the universe its name. They are 12- to 20-foot-tall (3.7 to 6.1 m) bipedal, armored, single occupancy military combat units. The Gears are less heavily armed and armored than main battle tanks used by the Terra Nova armies. However, the Gears provide a mix of capabilities that prove effective as the setting/game rules typically allow victory through maneuver warfare and place less emphasis on raw firepower and armor.
Several major wars take place over time, including the War of the Alliance. A new dictatorial government on Earth attempts to re-take its former colonies by force using its own advanced war machines such as hover tanks and armies of purple skinned GREL super soldiers (Genetically Recombined Experimental Legionaries). In this war both the North and the South cooperate to fight off the Colonial Expeditionary Force, which during their first defeat and withdrawal abandon many personnel (both human and GREL), who eventually settle Terra Nova and form the city-state of Port Arthur.
As of 6132 AD (TN 1936, local calendar), the Confederated Northern City-States (CNCS) and the Allied Southern Territories (AST) are recovering and rebuilding from the War of the Alliance. Despite the looming common threat posed by the eventual return of Earth's colonial armies, the polar superpowers have great fear and animosity for each other, an analogy of the real world NATO and Warsaw Pact, while the independent City-States of the Badlands simply try to survive the crossfire.

## Confederated Northern City-States

The political situation on Terra Nova has three major nations of the north polar region banding together to form their alliance called the Confederated Northern City-States to oppose the Allied Southern Territories from the south pole.

### Northern Light Confederacy

A large nation known for its devotion to the major religion of Sorrento Revisionism based on the teachings of an early wandering desert colonist prophet named Mamoud. Sorrento Revisionism is a sect that preaches conservatism, and the necessary use of force to make the world a better place. They are most often motivated to conflict by that reason, and even incorporate chaplains into military units.

### Mercantile Federation

An industrial power that puts a price on everything, including buying and selling votes in their political system, and has a keen interest in exploiting the untapped resources buried in the sand and rock of the Badlands.

### Western Frontier Protectorate

A region of open plains and ranching that promote family, hard work, and patriotism by military service. Indeed, the WFP requires a person to be a reservist in the Protectorate armed forces in order to be elected to high office, and only military veterans may vote.

## Allied Southern Territories

The south pole of Terra Nova likewise has an overall political grouping known as the Allied Southern Territories. Unlike the three nations forming the CNCS, which are generally on an equal level with one another politically, the Southern Republic dominates over the other three southern nations in order to field the strength necessary to meet Northern aggressive policies towards them.

### Southern Republic

The real power of the southern pole. They are the largest nation on the planet with both territory and population, and dominate the other southern nations by military force if necessary. They are openly free with many individual rights of expression, a high level of art and culture, and legalized vices, but with the major exception of freedom for political dissent. The government is intolerant of dissent and opposition groups, and employs secret police. Prisoners often form poorly trained and equipped military units.

### Mekong Dominion

A nation of manufacturing, money lending, and corporations as government. They are also minimally armed, using their small military as a dual purpose police force and often hires outside forces to supplement their own when necessary.

### Humanist Alliance

This nation uses science and technology to structure their society in an attempt to create harmony and utopia. This ideal has almost attained religious status in their people. They place citizens into castes based on aptitude testing and are highly educated at all levels. Research and development, and an efficient skilled work force are some of their greatest assets.

### Eastern Sun Emirates

A fractured nation of individual City-States that are almost nations unto themselves. They are led by hereditary monarchs known as Emirs who rule over their common citizens with no middle class in between.

## Minor powers on Terra Nova

Along with the major polar regions, several smaller factions exist on Terra Nova.

### Peace River

An independent city state in the Badlands of Terra Nova. They are an industrial nation capable of sophisticated, but practical manufacturing. This nation is home to Paxton Arms, one of the few independent corporations outside the two polar regions to build military hardware, including Heavy Gears of their own design. Peace River is the largest independent nation in the Badlands. The Peace River military also tries its best to defend other badland nations from encroachments by either polar League, but is often stretched thin to cover such a vast area. Their other major conflicts involve Rovers, the bandits of the Badlands.

### Port Arthur

The remnants of the failed expeditionary army sent by Earth to reconquer Terra Nova, Port Arthur was one of their primary staging bases in the Badlands. Over one-hundred thousand human officers and GREL (Genetically Recombined Experimental Legionaries) super-soldiers were abandoned by the Earth fleet concentrated on Port Arthur. From here they have established a nation for themselves, and benefit from the high technology of the Colonial Expeditionary Force (CEF) hover tanks, and GREL infantry to safeguard their territory.

### Rovers and independents

Most people in the Badlands owe their allegiance to no nation. They live as families, gangs, or individuals. Small facilities of human habitation known as Oasis Towers are spotted around the Badlands at any available surface, or shallow wells of water, and small-scale agriculture can even be attempted. However, most Badlanders make their living as miners or caravan traders. They ply back and forth between the polar regions and far flung industrial sites of the Badlands selling and buying goods.
Rovers are the criminal element of the Badlands. They are groups of local outcasts, criminals escaping the law, deserters fleeing their homelands, simple runaways, or even hereditary rovers born to other rovers who live in the wilds of the badlands and prey on local trade caravans, independent miners, and homesteaders.
They are a common problem in the lawless Badlands. Rather than work for their living, they take from others. Most Badlanders protect themselves in some fashion, though an unwritten code has developed over time where Rovers only take enough for themselves, and will not leave their victims destitute or without the supplies to survive. However, the cruelty and/or humanity of the Rover bands runs the full spectrum of decency. Many Rover bands even operate Heavy Gears salvaged from forgotten battle fields, stolen, or even bought on the open or black markets.

## Heavy Gears

The namesake machines of the universe setting are the Heavy Gears. They are 12- to 20-foot-tall (3.7 to 6.1 m) machines usually weighing between 5 and 12 tons, that resemble robotic humanoids. They seat a single pilot inside the chest and head unit. They provide a flexibility to the battlefield of Heavy Gear setting that make them more useful than most other units, though they do not dominate. They can traverse more difficult terrain faster, and change direction swifter than tanks, which is important to a setting that emphasizes mobility, and not just firepower.
They are powered by a unique hydrocarbon-burning piston engine called a V-engine, often mounted as a backpack. This is different from most science fiction settings, which use some form of nuclear power or a more obscure or invented power source. Confusingly, this V-engine is not the same design as a modern V-engine, but an alternative working design invented by students at the University of Colorado. The engine has two rotating cylindrical engine blocks with multiple chambers in each block. The blocks somewhat resemble large scale cylinders from a revolver handgun. The two rotating cylinders are set approximately 90 degrees from each other, and shared between each rotating block are several solid V-shaped rods that serve as pistons. As the blocks rotate inside static housings, openings in the sides of the rotating and static portions of the engine will line up and act as intake and exhaust ports, and electrical contact connections trigger the spark plugs. The rotation of the cylinder blocks is tapped for electrical power generation or directly for hydraulic pressure.
The computer system that enables the machines to move and operate fluidly are called Optical Neural Networks, or ONNets for short. They are learning computers that work, in many ways, similarly to an organic brain and are trained to perform advanced tasks instead of being programmed with software. They operate using light instead of electricity, and use microscopic crystals to form logic circuits for the light to pass through. New connections are made over time by the computer and allow it to learn new instructions. This factor leads the ONNet computer to develop traits, instincts, and habits over time based on the pilots that operate with them. Some functions become automatic as the computer tries to predict what the pilot wants and has used in the past in similar situations. This allows faster reactions in most situations, but can sometimes also cause indecision on the ONNet's part if tactics or patterns change in an unusual situation. Heavy Gear pilots tend to form a bond with their Gears' ONNets, or at least recognize the efficiency that an experienced ONNet provides; pilots forced to abandon a damaged or disabled Gear often take with them the ONNet unit from beneath their seats.
The weaponry of the Heavy Gear is usually lighter and less powerful than a main battle tank, as Gears themselves typically weigh only a fifth (or less) the weight of a tank. They typically have one automatic cannon carried as a Gear sized hand held assault rifle. They also typically have a shoulder mounted multiple-launch missile launcher rack, as well as a small anti-personnel fragmentation grenade launcher for use against infantry. However, variants of many machines, especially heavier models, can carry or mount a wide variety of weapons, such as heavy mortars, bazookas, guided missiles, larger hand-held grenade launchers, larger cannons or artillery, and even advanced directed energy weapons.
Heavy Gears can walk, run, crawl, and generally mimic most of the mobility of the human form, on which they are patterned. This flexibility affords the Heavy Gear many of the advantages of an infantryman, such as the ability to traverse difficult terrain and make effective use of cover, while at the same time having the resilience and firepower of a light armored vehicle. Most Gears also have a secondary movement system consisting of wheels (or tracks for heavier gears) fitted to their feet, powered either by efficient electric motors or a drive train connected to the V-Engine. The use of the alternate movement systems afford a higher speed and increased fuel efficiency on roads or flat terrain, and reduce wear on leg joints when traveling long distances. However, the wheels sacrifice maneuverability and cannot be used in rough or soft terrain due to their relatively small size, requiring the Gear to switch back to walker mode.

## Artwork and design

The Heavy Gear books are notable for their heavily illustrated content. Each book features highly detailed plans and cutaways of the machines, along with flags, insignias, maps and other visual information to help players' immersion. Most of the artwork was done by illustrator Ghislain Barbe, who was also responsible for the artwork of Jovian Chronicles, another Dream Pod 9 game. Although he left Dream Pod 9, Ghislain produced book covers for the Heavy Gear franchise until Heavy Gear Blitz! Locked & Loaded. Currently, artwork is provided by a team of individuals; Avelardo Paredes, Mariko Shimamoto and David Tauzia, among others.
The main themes of many artworks include the Heavy Gears themselves, with distinctive backpacks for the V-engine, single 'eye' head units, and at least a small area of the machine painted with an alternating yellow and black warning stripe paint scheme.
Northern military combat machines are typically shaped with rectilinear right-angled armor plates, and are usually named for predatory mammals such as bears and large cats.
Southern military machinery usually include numerous curved shaped armor plates. They are usually named for reptiles, often snakes.

## Rules

All editions of Heavy Gear use some variation of Dream Pod 9's own Silhouette game system. The first and second editions of the game contain both Role-playing and Tactical Wargame Rules. "Tactical" Heavy Gear calls for the use of hex maps and paper counters or miniatures.
The third edition of the Heavy Gear RPG uses a separate Silhouette CORE Rulebook, which is needed for play. The Heavy Gear 3rd Edition book contains useful summaries from many 2nd edition products, combined with some detailed statistics for both the SilCORE and OGL D20 systems.
Heavy Gear: Blitz! Locked & Loaded is the most recent Heavy Gear: Blitz! rulebook, the first of which was released concurrently in 2006 with a new line of miniatures. It contains no role-playing material and is styled as a dedicated wargame; it contains a streamlined rule system, an innovative new army building system, complete army lists and background information for five factions, a basic campaign system, a painting guide, and a timeline of historic events in the Heavy Gear universe. The Heavy Gear: Blitz! rules are intended for use with 1:144 scale model terrain, but it is still possible to use hexed mapsheets and paper counters.
The Heavy Gear Blitz! ruleset was a nominee for the 2007 Origins Award for Best Miniatures Game or Expansion of the Year.
In May, 2009, Dream Pod 9 released "Return to Cat's Eye", the first expansion book for Heavy Gear Blitz!, which provides background information and army lists for three new armies.

### Silhouette CORE RPG Rules

The Silhouette RPG, known in later editions as SilCORE is a simulationist system that defines characters in terms of 10 base attributes (agility, knowledge, etc.), 5 derived attributes (health, etc.), and a variety of skills. Skill rolls make up the "backbone" of the system, while basic and derived Attributes serve as modifiers to the roll.
The task resolution and tests involve rolling a number of 6-sided dice, taking the highest result, adding in modifiers for attributes and/or situation, and then comparing it to a set threshold number. If the result is higher than the threshold the test is a success; if it is lower the test is a failure. The margin by which the test succeeded (Margin of Success, MoS) or failed (Margin of Failure, MoF) helps to determine the outcome. Characters may suffer penalty-inflicting wounds rather than depleting a set number of health points.
Some players regard the system as particularly lethal, especially for inexperienced characters. A variety of optional rules are available in the SilCORE rulebook to mitigate this lethality.
DP9 ceased producing RPGs between 2006 and 2008 for their entire game catalog, including Heavy Gear.
On August 27, 2008, Steve Jackson Games announced that they had entered into an agreement with Dream Pod 9 to produce a fourth edition of a Heavy Gear roleplaying game. The project never got past the planning stages, however, and on August 9, 2010, Steve Jackson Games announced that they were relinquishing the rights to Heavy Gear back to DP9.
Dream Pod 9 announced that they would produce a fourth edition of a Heavy Gear RPG themselves, with a tentative release date of late 2011. This edition was not published.
In May 2023, Dream Pod 9 announced the coming of the official 4th edition rules for Heavy Gear, funded by crowdfunding to raise money for production and art costs. The project was fully funded and plans for a Q4, 2023 release are still in place. This marks the first new product for the Heavy Gear RPG line since production ceased in 2008. This new edition is reported to be compatible with Dream Pod 9's Heavy Gear Blitz! miniatures game as well as being backwards compatible with all Heavy Gear 2nd Edition rulebooks.

### Heavy Gear 20th Anniversary Edition

On March 5, 2014, Dream Pod 9 announced that a new Heavy Gear RPG would be produced by Arkrite Press LLC, which is co-owned by Dream Pod 9 staff members.

## Heavy Gear Fighter

Heavy Gear Fighter is a stand-alone two-player card game set in the Heavy Gear universe. It was published by Dream Pod 9 in 1994, and is currently out of print.

### Game description

Heavy Gear Fighter is a card-based dueling game in which two Heavy Gears duel in the Badlands. It is not a collectible card game; everything needed to play is contained in the box.
Every playing card is illustrated with a full color picture of a Gear. They are divided into Attacks of various strengths, Defenses, and Special Effects. Both players draw from the same pile.
The game does not use dice or paper. Each playable Gear has a full color record/action sheet that is used to keep track of actions/damage with small counters. Cards are dealt from a player's hand to cause damage, defend against enemy attacks, and create various special effects.

### Expansion sets

The game received an official expansion set, Equipment & Weapons, in 1995. As its name implies, it added new Equipment and Weapon cards that could be played on the Gears.
Several "mini-sets" were included as promotional material in the pages of various magazines, notably Mecha Press and White Wolf Magazine. These cards were always optional and allowed players to create special combat conditions as well as execute different maneuvers.
A set was designed that would have featured new vehicles (notably tanks and Striders), but it was never published.

## Miniatures

Heavy Gear has had three successive lines of wargaming miniatures starting with the RAFM produced 1:87 scale line, then the in-house produced 1:144 scale Tactical Rules and varying scale Fleet line, and the current 1:144 scale resculpted line for Heavy Gear: Blitz!
The 1:87 scale RAFM line was launched in 1995. The miniatures were largely cast in lead until public safety concerns, originally raised in 1993, influenced the gaming industry to cast lead-free miniatures. The price increase from the adoption of lead-free pewter made Dream Pod 9 reconsider the size and scale of their miniatures. As a result, the RAFM line of Heavy Gear miniatures was discontinued and never expanded beyond the Northern and Southern Terra Novan factions.
The 1:144 scale (12mm) Tactical Rules line was launched in 1997. It was largely the result of a desire to decrease the production cost inherent in lead-free, pewter miniatures. The Tactical Rules line was also developed with a greater attention to the control of proportions of the various Heavy Gear designs using computer-aided design illustrations as guides. The Heavy Gear miniature range was then expanded beyond the Northern and Southern factions to include designs from the Badlands and Colonial Earth Forces factions. The later Tactical Rules line miniatures were sculpted by Philippe Ferrier Le Clerc, who joined Dream Pod 9 in 2001. He also provided Heavy Gear limited edition resin miniatures through his boutique studio, Minimaniak.
During the same era as the Tactical Rules miniatures, Fleet Scale miniatures were also introduced which ranged from 1:350 scale for infantry, tanks, heavy gears, and striders to 1:3500 scale for landships.
The 1:144 scale (12mm) Heavy Gear: Blitz! line was launched in 2006. It preserved some of the Tactical Rules line miniatures for recasting. However, the majority of the Tactical Rules line miniatures will be resculpted. The intention of this change was that the miniatures bear a closer resemblance to the original hand drawn illustrations, that they have a greater range of possible poses, and that unit recognition is made easier for overall improved gameplay. In order to accomplish this, the difference in size between some miniatures has been exaggerated by approximately 10% and the miniatures are now cast on sprues, which allows many smaller, modular parts to be cast. Another effect of the Heavy Gear: Blitz! line of miniatures has been an appreciable increase in detail due to new sculpting and resin-master casting techniques. It has also produced the first new Heavy Gear designs in many years.
Fusion Models has also produced a 1:35 scale resin model of Heavy Gear's Kodiak heavy assault Gear.

## Video games

Faced with the loss of the BattleTech-MechWarrior property, Activision's Production Executive, Frank Evers (CEO), spearheaded the acquisition of the video game license in 1995. The first game, Heavy Gear, was released in 1997. The second game, Heavy Gear II, was made in 1999 for the Windows 98 operating system.
After years of the franchise laying dormant a licensing deal was announced on August 1, 2012, between Stompy Bot Productions and the owner of the franchise Dream Pod 9. A Kickstarter campaign for Heavy Gear Assault was launched but eventually cancelled in 2013. The game relaunched in 2015 in early access. The game is developed by MekTek Studios and published by Stompy Bot Productions for Windows and Linux. It's being developed with Epic Games' Unreal Engine 4 and was scheduled for a full release in 2018. As of 2020, Heavy Gear Assault is available for purchase on Steam, but, according to several reviews, the servers are no longer in operation, preventing the game from launching.

## TV series

In 2001, a computer-animated TV series titled Heavy Gear: The Animated Series was produced by Audu Paden at Mainframe Entertainment and Adelaide Productions for Columbia TriStar Television. The series lasted 40 episodes (though two of these were "recap" episodes and more still were clip shows). It played in syndication in various markets worldwide.
The Dream Pod 9 creative staff had very little input in the series' content, and the animated universe differs significantly from the game's. The show was aimed at an audience much younger than the one the property had previously targeted. The producers' original intent was to start the series with a mecha-combat tournament held between the villainous Vanguard of Justice who are like the Legion of Doom and the honorable Shadow Dragons (representatives of Terra Nova's Northern and Southern armies respectively) like the Mighty Morphin Power Rangers, but after the resolution of the tournament storyline rising tensions would lead to war between the North and South, which would in turn be followed by an invasion from Earth trying to reconquer its old colony planet, forcing the North and South to join forces for their own survival. Worries that having the villains from the early episodes (the Vanguard characters) suddenly working with the heroes, and shifting from a tournament-styled competition to all-out mecha warfare, would have been too confusing for their targeted age group led to a decision to not use the war storyline. What ended up happening on the show was that they ran the tournament storyline as planned but even though the tournament had been 'won' within the first dozen or so episodes, the two teams just kept having exhibition matches for the remainder of the 40-episode run. The series starred the voices of Lukas Haas, Vanessa Estelle Williams, David DeLuise, Ed Hopkins, Clancy Brown, and Clyde Kusatsu with Charles Shaughnessy, Greg Ellis, Karen Maruyama, Keith Szarabajka, Nicholas Guest, Jim Wise, Sarah Douglas, and Tom Kane.
The "in-universe" explanation for the difference between the universes is that the animated series is a Terra Novan entertainment program not unlike real-world professional wrestling.
In 2002, Heavy Gear: The Animated Series was nominated for a Golden Reel Award for Best Sound Editing in Television Animation.
DVD releases include two volumes released in North America in 2002 by Columbia TriStar Home Entertainment each with five episodes edited together into "feature length" stories. 2004 saw a release in the UK of a two disc Season One set including both "feature length" stories and three standalone episodes which collectively present the first thirteen episodes of the series in one form or other, but lacks the bonus content present on the North American releases. Also in 2004 Anchor Bay issued a single disc release in Canada with another five episodes from later in the series.
The entire series was formerly available for streaming for free in the US and Canada on Sony owned Crackle. It was also formerly available for streaming in Canada on Netflix.
The episodes were originally produced in widescreen and presented as such on the DVD releases, while most syndication broadcasts were of a cropped pan and scan version of each episode. The streaming versions formerly available from Crackle and Netflix were also of these pan and scan versions.

## Reception

In the February 1998 edition of Dragon, Rick Swan reviewed both the Heavy Gear setting and the Jovian Chronicles setting (also published by Dream Pod 9), and praised the high production values: "Both are beautiful games, into which a lot of effort has been invested." Swan admired the "Silhouette" game system for character creation, "the smartest set of universal rules this side of the GURPS game." But he criticized the combat rules, which he called "more work than fun." And he did not like the "downright dismal" setting, nor the paucity of information about its history. "Heavy Gear purports to tell the tale of the aftermath of the War of the Alliance, when Terra Nova was invaded by Imperial Earth. But there’s next to nothing about the history of the war or the effect on the participants. And don’t expect much about politics, culture, or economics. Put it this way: the entire 'World of Heavy Gear' chapter fills only six pages." He concluded with an ambivalent shrug: "Other than the lifeless settings, I couldn’t find anything seriously wrong with Heavy Gear... But I couldn’t find much to be excited about either."
In Issue 13 of Arcane, Jim Swallow reviewed Heavy Gear Duellist's Handbook, and commented that "There's plenty of source material for campaigns, with data on NPCs. locations and the welcome addition of more maps." Although Swallow gave the game a below-average rating of 6 out of 10, he concluded, "This is certainly a good place to begin a Heavy Gear game."
