What an immersive game. The ambiant is very good. Sometimes reminding me some "Demolition man" sounds effects.. xD The game has 2 differents gameplays; turn based or simultaneous. It gives the game different strategies. If you play with friends on your computer you will play turn based, while if you want to play with 7 friends on internet you will play with simultaneous turns. :) (I'm not sure what's the limit without MAX-Revolution ... same as single-player?)
