Weapon Guide

There are a wide variety of weapons available in RimWorld. Using them effectively can give you a sizable advantage against raiders.
== Overview ==
There are three main categories of weapon this guide will cover:
* Melee - Weapons made for close combat. Pawns are unable to fire guns at melee range, so these weapons have a wide variety of uses, from using hallways to bring enemies to you, to rushing a troublesome centipede.
* Ranged - Weapons that attack from range. There are a wide variety of ranged weapons, from the all-rounder generalists to "specialist" weapons that fit a specific niche.
* Explosive - Grenades, launchers, and other oddball weapons/utility items like the doomsday rocket launcher. In addition to raw explosions, many grenade-type weapons have a special effect, like molotov cocktails starting fire. Most explosives do not rely on accuracy, Shooting skill, Manipulation, etc.
There are also three technology levels to consider:
* Neolithic - Bows, spears, and clubs. Often necessary when starting a Lost Tribe or Naked Brutality run, but usually it is quick to replace them. (Tribal)
* Early Industrial - Weaker firearms, like pistols. These weapons are often carried by early pirate raiders. For the purposes of this guide, this includes any gun from Blowback operation and before, as well as medieval technology like longswords and greatbows. (Earlygame)
* Modern / Spacer - Weapons from Gas operation onwards. Even an endgame colony can find industrial era weapons viable - charge rifles and miniguns aren't always the best weapon just because they are higher tech. (Midgame)
=== Weapon stats ===
There are a couple of stats that are particularly important to consider in a weapon:
* DPS: Damage per second (at a given range), taking into account raw damage, accuracy, firerate, burst count, and armor. This is the primary consideration for most weapons, and for melee weapons in particular.
* Damage type: Whenever a weapon checks Sharp, Blunt, or Heat damage. Most ranged weapons deal Sharp damage. In addition, each specific damage type (Arrow vs ArrowHighVelocity, for instance) can have different chances to hit different body parts.
Ranged Weapon Stats
* Accuracy: For 2 weapons with the same DPS, a more accurate weapon hits targets more consistently. Certain weapons are more accurate at certain ranges. The pawn stat, Shooting Accuracy, is separate to the accuracy of the weapon itself. For a full breakdown of mechanics see: Weapons. Due to the specific mechanics of the Shooting Accuracy stat, weapons that deal the majority of their DPS at closer ranges lose less of their DPS than those that do less damage close up but more evenly spread their DPS across a wide band of ranges. Thus, weapons in the former category are considered "skill friendly", and those in latter are best relegated to pawns with high shooting accuracy. 
* Range: How far a ranged weapon can fire. Whether firing from this range is actually effective is another story.
* Firing Cycle: Fire rate of a ranged weapon - the combination of warmup, cooldown, and firing time. For the same DPS, a lower firing cycle makes a weapon more flexible, and better for kiting strategies.
* Stopping power: A stopping power of 1 or more can stagger, or slow, humans and human-sized enemies. Specifically, if stopping power >= body size, then the enemy will be slowed.
== Melee ==
Melee weapons specialize in hand-to-hand combat.
Pawns who are adjacent to each other are forced into melee combat, even if they are wielding a shotgun. A gun's barrel is quite ineffective compared to a sword. Melee lends itself well to disruptive tactics, like rushing down a sniper or grenadier, or peeling off enemies from your gunners. The melee block - create a chokepoint with 3 melee outside, where only 1 enemy can melee at a time - is extremely effective. You can have gunners fire just behind them.
The main con with melee is that damage is unavoidable. Later in the game, and especially with higher difficulties, enemies will vastly outnumber your colony. A 200 tribal raid will eventually wear down your most well-geared melee fighters, even in the best scenarios. The second con is that melee fighters will often have to approach ranged fighters, meaning it quickly becomes weaker in those situations. Animals will always fight back against a melee weapon, even against a 0% manhunter, making them terrible for hunting.
Notes:
* Give your best melee pawns the strongest melee weapons, assuming you desire to get into melee at all.
** Weapon quality and material has a large impact on any weapon's effectiveness.
* Shield belts are invaluable to give protection against bullets. They give melee pawns a new use - to serve as tanky distractions.
* Try to avoid using melee in the very early game, unless you outnumber the enemy. Ranged weapons and spike traps are stronger than the weaker melee choices.
=== Sharp ===
* Persona monoswords are the strongest sharp weapon, followed by regular monoswords.
* Plasteel or bioferritelongswords are the best craftable sharp weapon.
Sharp weapons are the bread and butter of melee weapons. They are the most common type of melee, dealing strong all-round damage. Most sharp weapons have the Cut damage type. Cut has a chance to "cleave" through body parts, increasing total damage but spreading it throughout body parts. 
:Comparisons:
When made of plasteel, a longsword of sufficient quality (2-3 levels above) can outdamage a regular monosword. A masterwork plasteel longsword will outdamage a good monosword, and roughly equal to a normal persona monosword, though it has less . Plasteel is much better than steel; a plasteel knife is roughly on par with a steel longsword of the same quality. The next best weapons after a longsword would be a spear and gladius. Faster weapons (like knives) have some niche to training melee.
=== Blunt ===
* Persona zeushammers are the strongest blunt weapon, followed by regular zeushammers . Both variants cause a small amount of EMP, stunning turrets and mechanoids for a short time.
* Uranium maces are the best craftable blunt weapon, and 2nd best overall.
** Uranium warhammers have a higher chance to 1-shot at high qualities, but are 3x as expensive.
Blunt wounds do not bleed and are often weaker in raw than sharp counterparts. However, blunt weapons are great for penetrating armor, as most items have a poor Blunt armor rating. They also have a small chance to stun for on hit.
Very high quality blunt weapons enjoy the superior damage propagation. If a sharp weapon would stab a finger, a blunt weapon would destroy the finger and smash the arm in the process. 
:Comparisons:
In terms of raw damage, zeushammers lose to monoswords until facing foes in marine armor, and persona zeushammers lose to persona monoswords until cataphract. Even centipedes don't have the Sharp% armor to resist a regular monosword. However, high quality zeushammers can start to one-shot humans, ironically making them better against unarmored humans than against centipedes.
Maces lose to longswords until facing flak vest-level armor, and longswords can still harm the unarmored areas of the body better. Like with monoswords and longswords, a masterwork uranium mace can beat a good zeushammer. Warhammers can 1-shot human sized enemies, or at least cause overkill damage. When available, high quality uranium warhammers are stronger against human pawns than maces.
=== Body parts ===
* Power claws are the strongest melee body part, but lowers Moving by 8%.
Artificial body parts can be used while holding a gun. Fulfilling the role of a sidearm, these implements are weaker than dedicated melee weapons. You can put these on your frontline gunners, who may not always be able to suppress a swarm of melee combatants. When holding a melee weapon, these parts can slightly increase damage; due to the melee verb system, sometimes the fists / body parts will be used instead of a weapon.
Creating these bionics is an advanced technology, so they are usually reserved for the mid- to late- game. Body parts can also be bought, though the surgery can be a bottleneck if you don't have a good doctor. Also note that pawns will prioritize their "best" melee attack; only one part is required for gunners.
:Comparisons:
Power claws are roughly equal to a normal plasteel longsword. Hand talons are stronger than elbow blades, which are stronger than a knee spike, though knee spikes have more . All three are roughly on-par with a normal steel longsword. Note that combat parts are incompatible with other artifical parts: hand attachments get in the way of a field hand, hand / arm attachments don't work with a bionic arm, and knee spikes don't work with a bionic leg. Venom fangs are the weakest of the bunch, but do not occupy any useful area of the body.
== Melee - Nonhuman ==
=== Animal ===
* Thrumbos are the best animal, but are notoriously difficult to tame and keep tame.
* Megasloths, elephants, rhinos, and both bears are behind the thrumbo, but can be found in the wild.
Animals are much more expendable than a colonist, and most have a lot more health than a colonist. However, they cannot be drafted, limiting their combat use severely. In addition, they require one or multiple pawns proficient in the Animals skill in order be tamed and trained. They thus have 2 main uses:
# Animals trained in Attack can... attack. They will rush towards nearby enemies, acting as a powerful distraction for your gunners.
# Animals can be put in an allowed area in a hallway raiders are passing through. Raiders and the animal will be forced to attack each other, resulting in a melee block scenario. Pen animals will not be attacked by raiders, and in any case are unable to be zoned.
Animal selection is also limited by biome, and large animals can turn hostile in failed taming attempts.
=== Wild animals ===
Other than shooting an animal and hoping it attacks the raiders, there are three dedicated ways to make wild animals hostile to your enemies:
* Psychic animal pulser is a single use item that turns all wild animals on the map manhunter.
* The manhunter pulse psycast turns all animals in a large, 57-tile radius into manhunters. Reusable.
* The animal warcall gene turns a specific animal hostile against your opponents.
For the former two strategies, you should wall in doors (to prevent exit via mental break), and watch the carnage. Stronger animals like megasloths or a herd of elephants can easily end smaller raids, or at least force sieges to attack. These are heavily dependent on your map's current fauna. Also note that using wild animals like this becomes progressively weaker as raids become stronger. An elephant can't handle 30 gun-wielding raiders, for instance.
=== Mechanoid ===
* Scythers are the most effective at melee combat.
Mechanoids have all the advantages of being an animal and then some, including the ability to be drafted like a colonist. Mechs can be repaired of all damage for just the cost of power and can be resurrected for a couple of steel. This negates all the long-term problems that lategame melee faces (though mechs are, of course, not invincible).
Mechs have their unique costs. They require their mechanitor nearby to actually control. They cost bandwidth, which could have been used for any amount of ranged mechs. And they create toxic wastepacks, which will eventually pollute your landscape. As combat mechs can be turned off, the actual costs of power and pollution are rather limited.
:Comparisons
Scythers (2 bandwidth) are the strongest and most effective at melee, and move slightly faster than a baseline human. Tunnelers (3 bandwidth) have twice the armor of a scyther and a natural 250 HP shield belt, but are much slower and don't do as much damage. Tunnelers can also mine. Centipedes (4) and mechanoid commanders (5) have similar armor to the tunneler, and have much higher actual health, though are mainly used for ranged combat.
== Ranged - Neolithic ==
Neolithic weapons are the easiest weapons to craft, available for New Tribes and Naked Brutality starts to craft.
=== Bows ===
Bows are a mid range, generalist option.
* Short bows are the simplest ranged weapons in the game, only requiring wood and a crafting spot. 
* Recurve bows are a direct upgrade to the shortbow, with an increase to damage, accuracy, and range, for only 10 wood more. Tribal starts begin with Recurve Bows unlocked, meaning they just need a Crafting skill of 5 to make these. At maximum range, recurve bows are surprisingly competitive with early firearms, especially at high qualities. (These can also be made at a crafting spot.)
Bows are at least something to fight raiders without having to engage in melee. Even without a single melee fighter, 5 tribals with shortbows can easily repel raids. Focus fire on 1 target, and don't let melee enemies too close. Doors can help with early ranged tactics. For example - place 2 doors on opposite ends of a larger building, and when melee raiders get too close, go to the door on the other side.
Naked Brutality players will want to rely on spike traps to kill raiders at first, using the shortbow for hunting and to save on traps. Of course, new tribes (and other colonies) can also use traps to their advantage.
=== Pila ===
Pila are incredibly short ranged support weapons.
* Pila lose even to a shortbow in raw damage. They have a small range and a massive cooldown, so are terrible as standalone weapons. However, the pila can stagger humans. The best use of the pila is a support weapon; place a low-skill fighter with a pila behind melee fighters. They also have some use as a hunting weapon. The high per-shot damage compensates for the lowered range.
Due to its weaknesses and Smithing requirement, pila shouldn't be actively created or sought after. However, a Lost Tribe will start with one.
=== Flamebows ===
Flamebows are specialist weapons that cause fire.
* Flamebows create fire on the tile it lands on. Watch out for your base. Pawns lit on fire will run around wildly, unable to attack until doused. Fire can also be used to quickly heat up any place considered "indoors", causing any enemies to get heatstroke and burn up. Special traps can be made to take advantage of the heat, just like with molotov cocktails. Flamebows cannot be crafted, only bought or dropped from impid raiders.
== Ranged - Early Industrial ==
Low-tech, conventional firearms. These weapons are often carried by early pirates and outlanders, such as the Scavenger Gunner, Pirate Gunner, and Town Guard. Scavenger gunners and pirate gunners in particular can only carry these weapons (and the incendiary launcher). These weapons will eventually be outclassed by superior firearms, like the heavy SMG and chain shotgun. So while you can craft these weapons as soon as you research Gunsmithing, many players like to wait to craft the weapons from Gas Operation and onwards, due to the large increase of effectiveness from the more advanced weapons.
Note that weapon quality has a large impact on combat. Even if you prefer revolvers, a poor autopistol will likely outperform an awful revolver, and a good recurve bow can outperform both (at maximum range). This applies to all weapons, but especially if you are reliant on obtaining weapons from raiders.
=== Handguns ===
Handguns are close-mid range, general combat options.
* Revolvers are a low-tier firearm with decent damage at the closer ranges. Unlike many lighter firearms, revolvers can stagger humans, slowing them slightly when a shot hits.
* Autopistols have slightly better DPS than revolvers at any range, but do not stagger humans. Autopistols also have the fastest cooldown cycle in the game, lending well to hit-and-run tactics against melee opponents.
As the lowest tech firearms, pistols are weaker than most of the options here, but still better than a recurve bow at all ranges. Inaccurate from max range. Both handguns are roughly the same as each other, but revolvers are better as a support weapon, and autopistols better as a main damage dealer.
=== Long ranged ===
These options are effective in any situation (outside of close combat), mostly due to the small effective range of contemporary weapons.
* Greatbows are on-par with most pistols, but have a higher range. "Greatbows are better than pistols at the pistol's max range". While costing only wood to create, actually researching greatbows is usually not worth all that effort - even for Tribal starts - when other guns are easy enough to get from raiders. Also, they are outclassed by the bolt-action rifle in every reasonable statistic.
* Bolt-action rifles are a fairly standard, mid-long range option, only outranged by the sniper rifle. Best range in this tech level by far, it can shoot just about any enemy as they approach. Like greatbows, they beat pistols at the pistol's max range. Good for open combat, and great for hunting. Preferably used with high-skill shooters. 
: Even when you have more advanced weapons, the bolt-action still has a niche. It deals more damage than the sniper while retaining high range. The bolt-action outranges all centipede variants, and comfortably outranges lancers.
Due to enemy AI firing from the closest available cover, meaning they often fire from near-max range, both of these weapons perform very well in the open. Both weapons are good in a long distance firefight, though bolt-action rifles are statistically superior.
=== Short ranged ===
Pump shotguns are a specialist weapon, great at both support and close-range damage. Machine pistols are strong up close, but a good overall weapon (for its tech level).
* Pump shotguns are both powerful and accurate - technically the most accurate weapon in the game, but have a measly 15.9 tile range. Damage is great, and shotguns can stagger pawns as large as centipedes. 
* Machine pistols fire a burst of 3 bullets with a very quick cooldown. Overall DPS beats both handguns up to 19.9 tiles, this weapon's maximum range. It even surpasses the pump shotgun at touch range (3 tiles). Fast cooldown cycle makes it good for hit and run tactics. A clear-cut winner if you don't have any better equipment.
Short ranged weapons are best used directly behind melee fighters, but remain decent at their maximum range. Like with melee, you can make hallways and tunnels so that you can gun enemies at an effective range. Counter these weapons by using a long range weapon, engaging them in melee, or luring them into spike traps before they get too close.
== Ranged - Modern ==
Ranged weapons unlocked from Gas Operation and onwards. Most, if not all, of these weapons have some sort of niche or viability even for late- and end- game colonies.
=== Rifles & SMG ===
Rifle-class weapons are generalist weapons, dealing great damage at any range.
* Assault rifles are perfect for open engagements, with good damage, above-average range, and high accuracy. They are very good when outside a killbox (such as repelling breachers and sappers), and respectable inside of one. If you don't need a sniper rifle's range, they are the best general weapon for kiting. Somewhat skill friendly.
* Heavy SMGs are skill friendly, close-medium range weapons. Great damage and accuracy up close, remaining decent at longer distances. A strict upgrade to the machine pistol. SMGs are best for low-skill shooters, mostly due to closer range. They can outdamage even charge rifles at <10 tiles, without the hard range restrictions of a chain shotgun.
* Charge rifles are high-tech versions of assault rifles. Stronger, and with high , but with shorter range and less accuracy. Charge rifles are the strongest weapon in a killbox that can remain flexible outside of one.
In general, these weapons are great for base defense, whenever in static setups or when dealing with breachers and sappers. They are also the best options for attacks outside of your base. Assault rifles are the overall best weapon outside of a killbox, charge rifles deal the most damage of the three, and SMGs are best at lower skill.
=== LMG & Minigun ===
Weapons with a large burst of bullets, but low accuracy and long cooldowns.
* LMGs fire a 6-shot spray of bullets. Can stagger humans, but lower single-target DPS than the rifles. The LMG is decent for crowd-control, and a good support weapon.
* Miniguns fire a massive 25-shot burst, a massively heavy SMG. High cost, wildly inaccurate, and with a huge cooldown cycle, miniguns are dedicated to crowd-control in specialized, stationary setups. Extremely powerful in the right situations.
Both weapons are good as support, and for at mowing crowds of enemies. Missed shots can hit other enemies in the vicinity, meaning their low accuracy is compensated when attacking a horde of tribals. Both weapons do well in crowded, stationary setups. The minigun is much more extreme - its optimal DPS is miles above any weapon in the game, but the user becomes a sitting duck. The LMG suffers when compared to rifle-class weapons, due to low effective .
=== Chain shotgun ===
A very high damage, decent accuracy, low range, specialist weapon.
* Chain shotguns are the strongest non-minigun, non-consumable weapon in the game, but with pitiful range. Perfect for drop pods and infestations.
Chain shotguns are amazing when you can expect or force close combat. Infestations are inevitable for mountain bases, while any form of melee block works well for shotguns. These weapons can also work very well inside a specialized killbox; if you can control/expect where sappers and breachers will go, shotguns can be a very viable weapon as a colony's sole firearm.
=== Sniper rifle ===
Extreme range, single-shot, specialist weapons.
* Sniper rifles have the highest range in the game, but low fire rate. Overall DPS is weaker than a bolt-action rifle, but snipers are clearly not a damage weapon. Useful for picking off sieges, lone centipedes, etc. Very reliant on Shooting skill.
Sniper rifles are great weapons for kiting stationary enemies and the best weapon for hunting. Fire a shot, and as enemies approach you, back off until they reset to their original position. They are also great at luring sieges to assault your colony, assuming the siege doesn't have snipers of their own. 
=== Charge lance ===
Medium-high range, single-shot, high AP.
* Charge lances have a large per-shot damage and high . However, its range is equal to an assault rifle, leading to a profile much similar to rifles rather than a sniper. Actual DPS is weaker than the assault rifle, and the armor penetration isn't actually that big. This gives it a weak niche, despite its cost and tech level.
Charge lances are very similar to assault rifles for overall usage, with same damage and range. As its DPS is lower, this weapon is not recommended to use over assault rifles, at least for most cases. It may have use in dealing with heavily armored enemies.
== Explosives ==
=== Grenades ===
Grenades have the shortest range of any colonist weapon in the game, only thrown up to 12 tiles. All grenades have a forced miss radius.
* Frag grenades are standard explosives. While powerful, they are virtually unable to hit a moving pawn without the player manually leading the target. Good for fighting enemies in cover. Can be thrown straight for a few tiles in a hallway, and coupled with their AoE and massive damage, they are devastating against massed melee enemies when placed behind melee blockers. Grenades are also very effective against structures and walls. Breaking a wall fast is rarely helpful, but this property is great for taking out mech clusters.
* Molotov cocktails create fire. Unwieldy, and with a small blast, molotovs aren't very effective to throw on top of raiders. Instead, fire can quickly heat up any place considered indoors, burning raiders and insects alive via temperature mechanics. Mechs are immune to fire and heat.
* EMP grenades stun mechanoids and turrets for a massive duration and break both shield belts and low-shield packs, but are harmless against organic targets. Invaluable for mech raids. Its blast radius is much bigger than the other grenades. As the blast is bigger than the forced miss radius, these are fairly reliable.
* Tox grenades create tox gas. This affects colonists and raiders alike, though you can outfit colonists with toxic protection. Tox grenades are best for attacking enemies who are passing through long, winding, and tight corridors, which have no recourse against the poison. Vents allow tox gas to transfer between rooms.
=== Launchers ===
Launchers have a greater range than grenades, but have a very long cooldown (2nd slowest in the game, just faster than the pila).
* Incendiary launchers create fire, like molotov cocktails, and just as unwieldy. Despite the range, it is no more accurate. Worse than molotovs for creating ground fires, as it shoots slower. As even molotovs aren't great to throw at raiders, these are most often outclassed by the thrown variant.
* EMP launchers stun mechanoids with EMP damage. They fire slower than EMP grenades, and have a much smaller blast radius than grenades; this usually makes launchers the worse option. While launchers do have a range increase, most mechanoids still outrange it, so this advantage is rather small. Note that Masterwork/Legendary quality launchers can stun longer than a grenade.
* Smoke launchers create blind smoke, which completely prevents turrets from locking on. Invaluable for taking out turret encampments and mech clusters. Smoke also reduces ranged accuracy for any bullet that passes through. Both colonists and enemies are affected equally, so can be useful to support melee attackers.
* Toxbomb launchers also create tox gas. Fires slower than tox grenades, but extra launcher range makes it better as a support weapon. Make sure colonists in the blast have some form of toxic protection.
=== Consumables ===
Weapons of mass destruction. Rocket launchers have a large warm-up and cooldown for the user. Targeters can be deployed quickly, but also takes some time to actually start the explosions. All of these are single use, and none can be crafted by a colony.
* Doomsday rocket launchers fire 1 large explosion, followed by smaller flame explosions. Extremely effective against humanoid raiders and lighter mechnoids, as a single launch can cause an entire raid to retreat. Available from trade or quests.
* Triple rocket launchers fire 3 explosions. Each of the three rockets deals the same damage as the doomsday's main explosion, though with a much smaller radius. Effective against mechanoids and structures in particular, and can still damage a raid quite heavily. Available from trade or quests.
* Orbital power beam targeters create a massive, fire-based beam centered on a target in line of sight. Incredibly powerful against humans, but useless against mechanoids. Can attack through overhead mountain. Quest only.
* Orbital bombardment targeters fire a total of 30 explosions over a large, 20-tile radius. Stronger than a doomsday against large groups, this item is also quest only.
* Tornado generators create a tornado at your map, on a specific point. This can possibly destroy player structures when used inside your colony, so is mostly useful for offensive operations (or as a last resort). Quest only.
As these are all rare, single-use items, use them for when you can't handle a raid, such as an extra-nasty siege.
=== Mortars ===
Mortars are not handheld weapons, but are weapons nonetheless.
* Mortars have a 500-tile range, but costs a mortar shell for each shot, and take to reload. With a massive Forced Miss Radius (9 tiles, reduced by Shooting skill), they are mostly effective against large, stationary targets. In addition, they require reinforced barrels every 20 rounds, unless Classic Mortars are turned on. With Classic Mortars shells become more expensive, and the mortar less accurate, to compensate.
Mortars are extremely useful against enemy sieges. Until they take enough of their own casualties, a siege will continue to lob their own mortar shells, which is devastating to any colony not under overhead mountain. They are great against other stationary opponents, such as crashed ship parts or mech clusters.
Each mortar shell has its own purpose:
* High-explosive shell: General purpose shell, good against any stationary target.
* Incendiary shell: Great for igniting a siege's own mortars/mortar shells on fire, potentially causing a chain reaction. But, as the game will start rain if a fire spreads too far, these shells aren't very useful otherwise.
* EMP shell: Stuns mechanoids. Massive explosion radius makes this somewhat accurate. Can also disable mech high-shields, so that other mortars can attack through the shield.
* Firefoam shell: Creates firefoam, extinguishing fires. The small firefoam radius and introduction of firefoam pop packs and foam turrets make this shell mostly obsolete.
* Smoke shell: Creates blind smoke in a large radius. As with the smoke launcher, it prevents turrets from locking on and reduces accuracy. While the smoke launcher is free to use, the shell has a larger radius and can be used from further away.
* Antigrain warhead: A weapon of mass destruction, on and above the level of a doomsday rocket. Quest only, so use it wisely.
