GTA: Command and Control
Enemy forces are on the way and they won't stop till your base is destroyed. You need to hold them off and fight back or they will destroy your base. There won't be anything to fight for if your base got destroyed. The idea here is to destroy the enemies or at least keep them in bay, meaning that you should be able to kill or destroy them before they can enter the premises. If you can kill them all, at least limit their number to a minimum. That is the plan here and you can win this.
