Our biggest release to date, 0.2 brings new playable units, a new gamemode, better mod support, and more!

The game is available for download here.


Introducing Builders, a new type of bot utilized by the First Expedition.

  • Researched in ResearchCenter.
  • Builders are now the only bots allowed to build buildings.
  • Like the Astronaut, Builders have the ability to scan for flat ground.
  • WingedBuilder can build while airborne.
  • Buildings built by a trainer Builder are also trainer.

Missions+, an alternative campaign with bonus content and additional challenges, optimized for a programming-only playthrough.

  • Includes a brand new mission on Volcano – Reverse Engineering, taking place between Transport and Analysis.
  • The mode provides additional challenges for players who have already beaten the game (although it is not a prerequisite):
    • Space Programmer – no radio-control, meaning this is a test of your programming prowess. Defeat your past self.
    • Space Researcher – by default Missions+ allow you to use all technologies you previously aquired, this challenge disables that.
    • Space Explorer – disables Astronaut’s abilities. As per usual your bots will have to do all the work. Fleshbag.

  • Added new PracticeBot types: TrackedTrainer, WingedTrainer, LeggedTrainer, HeavyTrainer, and AmphibiousTrainer.
  • All trainer bots (apart from TargetBot) now differ visually from their normal counterparts.
  • Trainer bots can now be built in BotFactory.
  • Buildings can now be trainers (a trainer BotFactory can only be controlled using CBOT factory() and will assemble trainer bots, etc.).

CodeBattle levels have been redesigned to utilize Builders and be more visually pleasing.

  • Levels are now split into two categories:
    • Training – a singleplayer mode for practice and testing your programs.
    • Versus – symmetrical 1v1 combat scenarios (challenge someone on Discord to an asynchronous duel).
  • Updated level layout, visuals, descriptions.
  • Added camera viewpoints.
  • Added enemy team AI in Training mode.

  • Heavy bots can now destroy bushes on contact allowing other objects to pass.
  • Added dedicated animations for plant destruction.
  • Recycler can no longer recycle small building ruins.
  • Thumper can no longer destroy buildings and mushrooms.
  • Thumper can now destroy the smallest Crystal, ground marks, Fireworks, Bushes and other small plants, Bag, ApolloModule, small CeeBot-Teen objects, and Barriers.

TargetBot is now a playable unit.

  • Researched in AutoLab.
  • Wrecks and ruins are now destroyable by ramming a TargetBot into them.
  • TargetBot is now more fragile and can be destroyed by Ants and Spiders, as well as water.
  • Updated Alien AI in Missions (some Ants will attempt to run from TargetBots).

  • Added new categories for exisiting objects: BrownMushroom, GreenMushroom, Ruin, Bush, GraviPlant, and Crystal.
  • Added new functions: flag() and deflag().
  • Added new types: byte, short, char, long, and double [@melex750].
  • Changed some functions from object-oriented to free functions in order to improve compatibility with CeeBot4 SCHOOL: factory(), isbusy(), takeoff(), research(), destroy().
  • Added automatic object detection for factory(), research(), takeoff(), destroy(), and camerafocus().
  • PracticeBot is now an alias for WheeledTrainer, TrackedTrainer, WingedTrainer, LeggedTrainer, HeavyTrainer, AmphibiousTrainer.
  • Added sizeof() operator for numeric data types [@melex750].
  • Restored repeat() instruction [@melex750].

Mod Manager allows the player to manage installed mods in-game.

  • Accessed from the main menu.
  • Can enable or disable each mod without the need to restart the game.
  • Shows metadata from the manifest.txt file.
  • Displays a list of subdirectories included in a mod to give a rough idea of what that mod adds/changes.
  • Mods can be reordered (if there is a conflicting file between multiple mods, the file from the last mod on the list will be used).
  • General improvements to reloading game resources on-the-fly.
  • The list of mods is stored in the colobot.ini file.
  • Added AltTextures example mod that replaces textures of certain objects.

  • Sniffers can now plant flags but can no longer scan for flat areas.
  • Added WayPoint animation for deleting ground marks.
