Darwinia is what life would be like in a computer. Single "polygon" organisms called Darwinians live their simple lives learning, growing, and dying to be reincarnated as other Darwinians. In the game, Darwinia is under attack by an evil computer virus, and it's up to you to bring it under control.

Darwinia was released back in 2005 on the PC to much critical acclaim, with a multiplayer add on created almost a year later.  The game puts players into a cyber world and mixes genres like real time strategy, puzzle, and action.  Your goal is to wipe the computer system of viruses before they eradicate your poor little Darwinians.
