An RTS (real-time strategy) game for the PC made by Relic Entertainment and Microsoft Games. Unlike other RTS titles, Impossible Creatures (or IC) requires you to make your own units with the army builder. The object of the game is to destroy the enemy's lab. In the original game, you get 50 creatures to mix parts with. However, there are many mods that add new creatures, Add-ons, maps, and abilities. The most popular mod currently is Creature Chaos, created by Revan and Doggiedoodle, who are administrators of the Impossible Creatures Hive community.

Some time ago, Microsoft Games took down the multi-player server for Impossible Creatures, however, another member of the Impossible Creatures Hive community, Dengus, has revived the IC Online service.
