Very good game. Is it possible to add online co-op to this game, where someone could be the mother or another survivor? Just like playing online with friends. Just a thought! =)
You should make a Halo Wars kind of thing, like have buildings where scientists can research advanced weapons and stronger, more skilled troops, SWAT or FBI maybe? Also you should put a vehicle depot where engineers can build police cars for cops to get around faster, or repair cables to call the army for backup, or an air strike or something. Just a thought. =D
