for Linux based debian package manager, you con add get deb ppa to get the latest release of this game.
I like this game especially for cross-platform multi-player mode. It's awesome!
Game is too complex. Too many units, too many weapons, too many upgrade paths. Cannon, machine gun, dual machine gun, flame, heavy flamer, rocket, mini-rocket array, on and on and on. One of the team colors in dark gray...in the fog of war so you can't even see where your units are. These developers must not even play their own game.
