Since I got hold of this game I have been hooked!
Btw make sure if you are running on xp makes sure you have sp3 installed. I had problems in the past on sp2 on this game a certain dual core processor driver was implemented in sp3 that solved a huge lag issue when used to put my dual core to 100% and lag the game. Recommend download the 360mb sp3 from Microsoft site instead of nasty auto updates that has mucked up plenty of PCs I know.
Game play is awesome! Level your troops get new weapons. Level up your troops through combat and end of mission reward. Unlock new missions once you conquered a map supremely.
Game play real addictive because its a strategy game that actually evolves the more you play! Missed it at 4.99 really wish I could get it at that price now being the new version is out in march.....
