Invincible Countermeasure

Invincible Countermeasure is a real-time strategy game in which the appearance and behaviour of units is determined by very small C programs, which can be loaded and modified at runtime. The game was created by Linley Henzell. It is free software, licensed under the GPLv3.

Linley Henzell is not working on Invincible Countermeasure anymore. He is using the game engine for a new game called Liberation Circuit:

IC was a fascinating development project but unfortunately didn't really work as a game - the RTS part was too drifty and slow and the programming part was impossibly complicated. LC should fix both of those problems: the action will be much faster and more exciting (and at 60fps instead of 30) and the API is vastly simpler and easier to use (as well as being optional if you want to use the designer instead of hand-coding everything).
