Colobot (Colonize with Bots) is an educational real-time strategy video game featuring 3D graphics, created by Swiss developer Epsitec SA. The objective of the game is to find a planet for colonization by the human race by establishing a basic infrastructure on the surface and eliminating any alien life forms endangering the expedition. The game takes place on the Earth, Moon, and seven fictional planets. The main feature of the game, which makes it educational, is the possibility for players to program their robots using a programming language similar to C++ or Java.

Plot overviewEdit

Life on earth is threatened by a devastating cataclysm, forcing mankind to move out and search for a new home. A first expedition composed solely of robots was sent to find another habitable planet. However, for unknown reasons, the mission was a disaster and never returned.

With only a few robots for companions, the player must travel to new planets. Houston, Earth Mission Control as well as a spy satellite will transmit valuable information to the player. The player needs to build the infrastructure necessary to gather raw materials, energy supplies, and produce the weapons necessary to defend themselves. By programming robots, the player can delegate tasks to them, allowing the player to continue their mission while their robots upkeep the base, fight off enemies, harvest materials, and perform any other tasks assigned to them.

Language overviewEdit

Bot in colobot

The programming language used in Colobot is CBOT, syntactically similar to C++ and Java. Example code for a bot to find a piece of titanium ore and deliver it to a purification facility:

extern void object::FetchTitanium()
	object item; // declare variable
	item = radar(TitaniumOre); // find a piece of titanium ore
	goto(item.position); // go to the ore
	grab(); // pick up whatever is in front of the robot (presumably the ore)
	item = radar(Converter); // find the ore converter
	goto(item.position); // relocate to the converter
	drop(); // drop the piece of ore
	move(-2.5); // back up 2.5 meters to allow the converter to start processing the ore


Epsitec released the games' source code in October 2014 under GNU GPL v3 after being contacted by the Polish game enthusiast community PPC.[1]

ICC & TerranovaTeam (formerly PPC[2]) was given the source code by Epsitec under the GPLv3 license.[1] Terranova is in the process of updating the game, titled Colobot: Gold Edition.[citation needed] They are also working on a sequel: Colobot 2[citation needed], aiming for a Steam release; however, this goal has not been accomplished yet.
