well, once i hit general, i was able to beat the game. i used mp5 until i could afford hk-417 (after opening up all the rooms) and i got 2 adws', then 1 vickers, then 2 more adws' and then 3 vickers. Outstanding game, looking forward to a SAS-Zombie Assult 3 (fingers crossed) p.s. i never once got upgrades for my bariers.
