Need some heftier firepower, the end game fights are a freakin marathon. Also the later bases don't carry the good stuff! Gotta go hunting for it when you want it, kinda a pain in the butt. Great game still!
Found a glitch in level 6 (hanger area, SE corner of the large hanger beside what looks like it could be a dumptruck) where I walked into a spider(?) hole that those little guys continuously pop out of and then just got stuck it in. Kinda sucked cuz i had to restart the level after reloading :(
