Zombie Army Trilogy, Playthrough Solo, Pt. 6

Lots and lots of zombies in this episode. I found one mini-boss trapped underneath a tank and he couldn't get loose. Heh, shot him in the head a couple of times which ended his evil career. Then found 3 bosses who kept producing zombies.. I tried the mini-gun they provided but turned out to be worthless and barely hit the incoming zombies (which turned out to be perpetual). Had to defeat the main boss and the skeletin heads around him. Three shots in the head ended and the incoming zombies. Episode completed!
