all depends on your tactics, if it doesnt work, change it, some maps you may need more resources[master craftsman] others you need better unit dmg, all maps are beatable, just takes a lot of trail and error
keep this voted up
heres a tip for the big star base, have in in range of your scanner, but far enough away it cant shoot you, then just fire, and dont bother with the havoc [CRAPD] system, useless, shields main weapon fire rate/regen are the better choices
the issues i find with the game is that some weapons, liker the rocket launcher, direct hits on the opponent, even with the dmg bonus wont kill them, but, they can head shot kill you with full hp and shields, hell even when your invulnerable with a bloody pistol, and reloads seem to be extremely slow during quick games
