Defend the offspring of the Brain Replicating Alien Drifter (aka BRAD) through 12 waves of ravenous undead. Rain down on them with every weapon at your disposal before they smash, headbutt and vomit their way through your defenses.
Protect BRAD's offspring through all 12 levels of zombie onslaught or try to rack up the high score by wrecking zombies in survival mode. Either way, you’re the last hope for repulsive aliens everywhere!
Minor bug fixes.
