Liquid War

Liquid War is an original multiplayer wargame. There are no weapons, the only thing you have to do is to move a cursor in a 2-D battlefield. This cursor is followed by your army, which is composed by a great many little fighters, represented by small colored squares. When fighters from different teams meet, they eat each other, it is as simple as that.

A single player mode is available, but the game is definitely designed to be multiplayer, and has network support.
