I've had no lag at all. 4/5 as it desperately needs an autofire (are you really going to stop shooting?) but is fantastic over wise. May get slightly boring after a while and powerups don't last long (maybe a shop or something?)
good, but 3/5 cus the enemy's have a big advantage. They get better vehicles before you do and the grid show most of their vehicles have a big advantage
300 spartans are easy. Max out a grenade luancher and an electricity tower and the wont touch you. also, fire ans many greade shell as possible at hte same time.
I think there is some cheating going on. If you look at the high scores list, some people are finishing with far more lives then you start with, and getting ludicros amounts of pionts - e.g. 2000000007 pionts, far more than most people. Looks a bit fishy... <><
