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!
The developers have had plenty of complaints about the AI to know. The behavior of trucks, mechanics and engineers is atrocious. It kills the best game I ever played. Losing a game because of trucks putting themselves in the line of fire is gutting. It is not military discipline and as cyborgs they do not have emotions. It remains a 3 to 4 star game. What a waste.
