very very very fun an' addictin', yus
It's pretty awesome... love the variety of mechs you fight against, and love the ability to swap weapons out mid battle, but like everyone else, I has issues with the four "Upgrades" things at the bottom. No mech purchasing (although I figured they could be unlocked after a campaign with the first hero... I also have a tendency to crash the game when there's too much ammo poppin' up n screen... I guess that's what it is, but it's pry just me... o' well, I still love the game :D
