But.. But... Alien zombies! Zombie aliens! ZAMBIES!You must not be playing it on a very hard difficulty, cuz I'm having trouble keeping ammo on normal mode.And even third world countries produce better weapons then EarthGov apparently. Have you seen the stock on the pulse rifle?

I'm pretty sure I beat it on the hardest difficulty, as I usually do when I get into a game.

I'm weird like that.

I just used the Plasma Cutter. You literally don't need anything else. I didn't have to spread out my upgrades or worry about ammunition.
