Planets

# About

    Planet Smash mode evidently includes several planets  the player may choose from to destroy with the weapons. The planets are made entirely from voxels, which allows them to all be completely destructible. Different planets have different core-depths (or no core at all, in some cases) which change how the planets cool after being cut through or hit. (This is evident via use of the lasers:  This difference between planets does not seem to change any actual reaction to the weapons (most often, the planets will suffer a small crater and a burnt area after a weapon hits, most likely exploding File:Explosion-small.png on the surface of the planet.).

All planets seem to have a "breakdown point"  where the rest of the population that lives immediately drops to zero and the planet has a singed, fiery overlay. This breakdown point  seems to be caused by successive constant damage (mostly by bombs  or black holes , or too much of other weapons (e.g. alien ships  (the shield can stop these attacks), usually when destroying a planet's core (completely), however it can happen from any destruction on the planet (e.g. removing too much of the total volume of the planet, with the LASER ), but it doesn't always happen when a core is removed. After this breakdown point, there is another stage after more damage is sustained which overlays the planet with a texture of magma and brimstone.  If the Sun  is exploded or a Planet Killer  is used and its beam  hits the planet, it will activate an animation where all voxels left will breakdown , crack and start to glow brighter and brighter until they all explode (technically, all the voxels get deleted at once) behind an epic animation of disintegration of the planet as its pieces disperse among the cosmos.

Half of the planets in the game are based on real life planets and moons in the Solar System, while the other half are completely sci-fi. Most populated planets have defenses of some kind (mostly nukes)  against certain types of attacks (usually alien spaceships  (), but also other weapons (in the case of the Dysonsphere Planet File:Dysonsphereshieldup.gif]]), e.g. the lasers  or falling space objects , among others. ). All populated planets appear to have a population map in the code which differentiates population densities and counts across the surface.

## Earth

*Main Article: Earth*

The human home planet, of course. Its cross-section is very close to the actual theorized layout of the Earth's layers with the thin crust, majority mantle, and the inner and outer cores. It has a population of 7.791 billion (previously 7.788 billion). Its population map is realistically designed - for example, the U.S.A has a little over 330 million deaths when burned (which matches the population now, or at least when the most current version was released), the U.K. has 66 million deaths when burned (exact U.K. population when rounded), India has over 1.35 billion deaths when burned (correct again), and China has over 1.39 billion deaths when burned (correct yet again). Very small city lights, that have cities with less than 1 million people, are not counted in the death count, even though there are people there. This makes it possible to have 0 million people alive, yet with city lights still on (i.e. not broken down , or all land voxels removed), simply because they were not counted in the statistics/population map.

The approximate location of Washington D.C., the capital of the U.S.A., and the approximate location of Moscow, the capital of Russia, both act as defense points for Earth against a UFO  (and possibly other ships' ) attack by sending nukes  to the spaceships  before they can attack within a radius. They can send multiple nukes  at once within a radius similar to the size of the singed area left by a successful spaceship ((usually ), but also ) blast, but can be too late when having to send nukes  to the outer edges of that radius, as player-fired nukes File:Birddrift2.png may destroy the surrounding area first, spaceships  can have already shot before being destroyed, or other weapons  - / - , etc. which destroys the capital's surface areas. The ships  then attack and remove more voxels.

### Other shapes

There are other shapes of Earth, accessible in the secret planet menu.

#### Flat Earth

    Using the LASER  (preferably set  to 5 power) to destroy most of the northern and southern hemispheres, to leave a disk-like remnant, then resetting  the planet, will make the Earth  Flat . Alternatively, set the grid so that only two axes are full. This will leave a disk-shaped remnant. Reset to flatten it. It's cross-section is massively changed compared to the standard round Earth , it's population is changed to 500m (very easy to kill all populations ), and there are 3 main issues:

1. The Laser Satellite  will start cutting at the central north pole, then cut more away before crashing into the planet File:Explosion-small.png. If used directly on the side, they will fire  and scrape off some of the planet's surface (the LASER  just touches the surface voxels, barely), then stop.
2. The UFO  can not effectively fire at anywhere other than the Arctic Circle. (It will also crash into the planet and explode File:Explosion-green.png.) If used from far away (likely from stopping behind a moon , or even Flat Earth's moon , then
3. The ForceField  does not defend correctly (shields  will pop up sideways, like a dome shape, just like the atmosphere.).

In newer versions, the Sun  and the Moon  are positioned directly above the Flat Earth. They are slightly different in operation, however:

Using the lasers  -  on the Sun  will invoke a Supernova, but instead of breaking down  and exploding , Flat Earth will just go dark and turn on all city lights.  The Sun , obviously being a source of heat, will also burn Flat Earth File:Flatearthburned.png if touched and moved off its normal position (it can fall down due to gravity , or more likely, being pushed (can be from any weapon) , etc.) The same reaction applies for the Moon , though being far less massive, it may just fly off course, with a small explosion File:Explosion-small.png. This moon  is a solid object, unable to be damaged like most other voxel-based planets (though it can be heated up like the standard Moon . It will also damage Flat Earth  if it hits it, though with a much smaller impact radius than the Sun , and is also far smaller than the weapon Moon  (a quarter its size, in fact.)

#### Donut Earth

    A donut-shaped Earth (formerly just called **Donut**) is available by cutting the Earth into a donut shape. It only has a population of approx. 3 billion, and the continents curve inwards.

To unlock this shape, use the same grid settings (two axes full/a flat plane) for the Flat Earth. However, after this, cut a hole in the center, big enough to be considered a donut's hole. Reset to get the donut-shaped Earth.

#### Cube Earth

    A cube-shaped Earth (formerly called **Cube *World***) is available in the menu, even after the game has just been installed (for the newest versions). Originally, it would have been presumably unlocked by cutting Earth into a cube, but the developers probably scrapped the idea, in favour of a perpetually-unlocked Cube Earth (it has been reinstated now).

Using the grid feature set x,y,z to the middle of the bar then put them down 1 (or half), from there just destroy the earth's unprotected areas, as everything in the grid is protected and so will not be damaged. Once it is a cube make sure it's all flat (cut away any small lumps), and then reset the planet.

#### Trick Or Treat

    A planet size pumpkin released as part of the halloween update. It is available in the “Unknown System” (question mark, ?) planet tab  and can be unlocked by either using the Planet Killer  weapon or exploding the sun  in a Supernova while on the Earth  planet (use a laser  - .). After one of them are chosen, wait until the planet is glowing bright orange, and before it explodes , reset the planet to get the pumpkin planet. It has a sun  of its own inside, but will explode in a Supernova harmlessly if lasered  - .

#### Moon

    The weapon Moon  is now a destructible planet in its own right. It now has a cross-section similar to #Ganymede , with its own texture. However, using its weapon now ejects a Ceres to impact the Moon, given its small[er] size. *Main Article: Weapons#The Moon*

## 1.1 Update Planets

### Mars

It is the red planet. Its cross-section has a thicker crust than Earth and no defined outer/inner core . It has no population or defense systems.

### Persephone

It is named after Hades' abducted wife in Greek/Roman Mythology, but is not based off of any real life planet. Its cross-section has a thicker crust than Earth as well as a larger outer/inner core. It has a population of 8.651 billion (previously, 13.372 billion) as well as another detailed population density map.

The one defense system it seems to have is on an island in the middle of a sea which is surrounded on 3 sides by a U-shaped continent. It seems as though this would be where the planet's capital (or at least a nation's capital) is based on the fact that the defense systems on Earth are at capitals. This defense system acts exactly the same as the ones on Earth, being that it sends a nuke  to each ship  in a certain radius from it.

This planet seems to be that of a sophisticated, advanced alien race because its cities are aligned in perfect circles across the planet with interconnected lines. The lights during the night identifying this could also be each city being the full size of these circles, rather than being separate cities for each light. \

## 1.2 Update Planets

### Ganymede

It is the largest moon  in the Solar System, one of Jupiter's  moons of the same name. Its cross-section has a much thicker crust than the other planets (similar to Boreas , or the Moon 's cross-sections) and a cooler core (like these planets'   cross-sections). It has no population or defense systems.

The breakdown stage of Ganymede. It does not feature any singed texture, similar to Boreas's breakdown.  ]] Unusually for an unpopulated planet, it once had its own breakdown stage, (in an older version where the blue LASER  was seperate from the orange one ) but it did not feature any singed texture, unlike the more populated planets, similar to the current breakdown  of Boreas .

### Machine World

It has a Dyson Sphere  in place of where the core  would be, which powers a strong energy shield defense system around the planet, and the planet is a metal spherical shell designed to look like some kind of futuristic city. This planet-wide city's population is 812 million (formerly, 7650 million) with a more evenly spread out population density map. (There is an unusual habit of city lights still being on, despite the planet's population being completely dead, not even reaching its breakdown or brimstone stage yet File:Machineworldbreakdown.png.) The energy shield File:Dysonsphereshieldup.gif]] is extremely powerful and can withstand the power even of several Planet Killers  at once. (In the newest versions, it takes at least three to take down the shield and generator , and destroy the planet . Formerly, the shield was even more powerful, requiring about ten Planet Killers  just to take it down, and even more of other weapons, for example many more black holes  (which, ironically, are now very effective against it. The same principle applied also to the lasers  ( and  are not very effective, or need hundreds of shots) and the Moon(s). ). The shield also stops:  -  (multiple can be used to take it down)  (they bounce off) ,  - ,  -  (surrounding it with enough can take the shield down),  (three can take down the shield and planet (File:Machineworldbreakdown.png, then )),  (will keep drilling/lasering  into the shield)  (although they enhance the existing shield, instead of damaging it, by stopping at the outer radius ),  (excepting , which will punch the planet with no resistance from the shield) -  (as long as the shield generator (the Dyson Sphere ) is up, both creatures will stop at the shield's radius and turn away, even if the shield itself is temporarily down ),  (unless deliberately driven to impact the planet File:Dysonsphereshieldup.gif]]),  - ,  -  (like the drill , it will keep drilling)  (will stop at the outer radius, but when the shield is temporarily down , it will not cause any damage to the planet ), File:Snowball.png (Will impact and freeze respective surface voxels/shield hexagons.))

Shield Going DownDyson Sphere
The LASER  -  when set to power 5  is the fastest at destroying the shield , especially because the LASER  -  can be used while time is paused, so you can effectively use up the shield's energy instantly in the simulation's time . The shield not only absorbs energy  put into it, but it also cuts off the gravity of the neutron star  inside the Dyson Sphere , when up File:Dysonsphereshieldup.gif]].

This can be tested by shooting bombs  at the Dyson Sphere  when the shield is down , which pulls them to it with gravity, then when the shield regenerates File:Dysonsphereshieldup.gif]], it pushes outward from the Dyson Sphere  until it gets to its standard radius, but the bombs  shot stay stuck to the innder surface until the shield is down  again. However, bombs  shot onto the surface of the shield do get pulled to it, and roll along it. While the shield is up File:Dysonsphereshieldup.gif]], however, bombs  themselves can also be used to destroy the shield, just by continously shooting at it (preferably in the aim mode). Enough bombs , attracted to the shield (and using up its energy), can destroy it , and they will fall onto the surface, killing inhabitants, and possibly even inside (and attract to the generator . These bombs  will go up to the inner surface when the shield regenerates File:Dysonsphereshieldup.gif]], and will only go down when the shield is deactivated again, damaging the planet, and attracting to the shield generator . Even more bombs  shot at the generator  can destroy it completely.)

When the shield is absorbing energy (especially from the LASER ) , it gradually goes from glowing blue, to white, to yellow, to orange, and finally to red before it has an animation for it going down . The shield takes exactly 11 seconds to regenerate File:Dysonsphereshieldup.gif]] (yes, 11). (The animation for regenerating File:Dysonsphereshieldup.gif]] is the same as the shield going down , but it is blue in color and reversed File:Dysonsphereshieldup.gif]].) The shield also regenerates File:Dysonsphereshieldup.gif]] whenever the planet is reset  (only in newer versions).

If the generator  takes too much damage, it will make a small explosion and the shield will no longer generate. If the sun  is exploded (or a Planet Killer  explodes the planet's shield generator , or touches any part of the surface with its beam ), it will bypass the shield (if up) without even affecting it, and will heat the metal material voxels of the planet with a redder color than the other planets' voxels (made of rock). Then, the planet will disintegrate and explode , animated over just like with other planet explosions .

Like the Purple Planet, the Machine World has another star .

### Venus

It is Earth's sister planet. Its cross-section is very similar to that of Earth's, but with a slightly thicker crust . It has no population or defense systems.

There is another planet, very similar to Venus, however it has white instead of brown clouds. It slightly resembles Saturn, though with a Venusian cross-section.

### Terraformed Mars

This planet is a fully terraformed Mars, most likely based on Daein Ballard's artistic representation. Its cross-section is exactly the same as the original Mars'. It has a population of 3.028 billion (previously, 3.644 billion) people with another detailed population density map.

It does not seem to have any defense system. The city lights are aligned as you'd expect from a new civilization, as they go in lines and then bubble out at random intervals. Also, most of the bigger patches of lights are close to water sources.

Terraformed Mars' City LightsThis artist's impression is likely the base for the existing planet's display in the game.
### Hades

    This planet resembles the Greek realm of Hell - red and lifeless. Its name is shared with Hades, the Greek god of Hell, otherwise known as Pluto . It has a ring of asteroids  (resembling Saturn's File:Saturn systemsmash.png) that are indestructible except for crashing into the planet itself. These defend the planet against destructible objects (mostly alien spaceships  (shields  will stop outside the ring of asteroids), but they can also be targeted by falling objects (mostly the energy weapons  - ) , but also most others, including  -  (yes, an asteroid  can hit another asteroid) ,  - ,  -  (they will either keep moving toward the asteroids or crash into them)  (will stop outside the asteroids ),  (excepting , which will punch the planet with no resistance from the asteroids, they will also be destroyed) - ,  - ,  -  ).). Its cross-section has a thicker crust and a slightly cooler core, like Venus' and Mars' cross-sections , and similarly has no population or defense systems. Its blue star File:Bluestar.png (or red  is also indestructible, requiring a Planet Killer  to destroy it .

### Custom Planet

A planet with which you can change the color of the vegetation, dry ground, and oceans, as well as the amount of water and the temperature (all these features are, by default, the same as Earth's . Its cross-section is also the same as Earth  but it has no population. The population (and city lights) can also be customised, now at a maximum of 103 billion people. Strangely, it also has its own breakdown and brimstone stage, for an uninhabited planet.

Changing the temperature changes the size of the ice from the poles; putting it up all the way removes the poles and vegetation; putting it down all the way surrounds the planet in ice. Changing the water setting all the way down removes all water; setting it all the way up makes it an ocean planet.

The color selector is finicky because the player's finger or mouse has to be held on it to get the game to recognize that the menu is being used, and a misclick/mistap in the areas between selectors causes whatever selected weapon (especially the planet killer , LASER , black hole  and Moon(s) ) to fire while still on the menu, which can destroy your planet  before being able to see the changes and effects after it is customized. This can cause some frustration as the player would have to reset  the planet, after the destruction, because of this bug.

Vegetation (left), Dry Ground (middle-left), Water (middle), Water Level (middle-right), Temperature (right). All are defaulted to Earth's  color scheme.Color Selector MenuWater Level and Temperature Sliders (defaulted at half, just like Earth's .)

### Ghost World

    The Ghost World is a purple planet made of a jellylike material, like the Nebula God  and the Cosmic Thunderstorm.  It is unlockable with the achievement (Punch Earth  or Snowman  to bits). To unlock it use the Nebula God and make it punch it until you get the achievement. Its debris is purple, like the main body of the planet, and it has no breakdown/brimstone stage, however it can still explode  when the Sun  explodes in a Supernova.

## 1.4 Update Planets

### Perchta

        Perchta is a gas planet similar to Jupiter, but redder in color and orbiting a red star . It shares many other features with gaseous planets such as shrinking when cut, down to a certain radius.

## Christmas Update Planets

        These planets were added in the version 1.3.7. However, they were removed then re-added, along with the Christmas weapons  to destroy them.

#### Boreas

It may be based partially on Europa, Jupiter's  Ice Moon. Its cross-section is the same as Ganymede's  (and the Moon's ), as it has a thick crust around a small, cooler core. It has no population or defense systems.

Unusually for an unpopulated planet, it has its own breakdown/brimstone stage, similar to Ganymede  in older versions File:Ganymedebreakdown.png (those with the blue LASER  as a seperate weapon .).

The breakdown or brimstone stage of Boreas (quite different to other, larger planets with populations. )Terraformed Boreas
Firing a healing missile at Boreas will terraform it, altough its population is still 0. Comparable to the Block World.

#### Snowman Planet

This "planet" is a simple snowman design made out of the same voxels as all other rocky planets. The coals and carrot are outer-layer skins (paper-thin meshes) of their shapes and are destroyed similarly to voxels. Its cross-section does not include any distinguishable, hot core. The voxels do not act similarly to snow or ice, unlike common thought. (It is easier to destroy than expected.) It has no population or defense systems.

In the newest versions, after being removed in the post-Christmas  update (then added back later the following year), the snowman planet was added back as a secret planet  (after unlocking the achievement for turning the planet completely to ice, with the ice laser beam ).

### Gingerbread Man

 File:Gingerbreadplanet.png      The Gingerbread Man is what its name says, similar to the snowman. Its decorations are also thin surface voxels. However, unlike the snowman's, and indeed all other decorated surface planets, their surface voxels are not removed when frozen  (but can be removed in other ways such as being crushed  or cut , or exploded .)

### Snow Globe

 File:Snowglobeplanet.png  The Snow Globe is what it's named... It has a shield much like the Dysonsphere Planet //File:Snowglobe shieldgenerator.png, but instead of energy shielding File:Dysonsphereshieldup.gif, it is made of a cosmic 'glass-like' voxel material. It shows cracks where objects hit it, from small impacts such as boxes , ball bombs , or even lasers. The interior shows a large Christmas tree  with decorative, indestructible baubles File:Christmasbaubles.png (that do not fade even when the Sun explodes in a Supernova), and a voxel-made 'rocky' base. To unlock it, toss many presents at #Earth, and open them with a snowball . The unlock earns an achievement for the snow globe.File:Snowglobeachievement.png

## 1.8 Update Planets

### Avalon

A world with 35 billion population. Its cities lie in circles of shapes and dots , and has tan land. It is modelled off STAR WARS' Coruscant.  Using the Planet Killer changes it to a tiny version of the #Machine World , and can fire a laser  very similar to the Death Star Superlaser. File:Planetkiller avalon.png

### Tatenen

An arid and desert planet in Tau Ceti. It has a population of 28 million, and its inhabitants seem to be in the middle or pre-industrial age, because in addition to the low population, they don't have any kind of defense system.
