Liquid War is a unique multiplayer wargame. Its rules are truely original and have been invented by Thomas Colcombet. You control an army of liquid and have to try and eat your opponents. A single player mode is available, but the game is definitely designed to be multiplayer, and has network support.
The award Liquid War received from The Linux Game Tome in 2002, for being the "Most Original Linux Game". It has been ranked "most original Linux Game" by the Linux Game Tome in 2002. It and has also been nominated in the games category at the internationnal free software contest "Les trophées du libre" in 2003. And I was pleased to hear that Liquid War has been distributed on CD-ROM by a fair number of magazines (essentially in Germany).
