There's two things that I love -- killing zombies, and being happily unproductive. Dead End from Infectious Entertainment lets me do both, and does it damn well. It's a top-down shooter, where you're stuck in a graveyard, facing wave after wave of bloodthirsty zombies. Here's what Infectious Entertainment says about it:
Zombies have killed your family, eaten your neighbors and destroyed your
city. Blinded by rage and seeking revenge, you go to the one place you know you’ll be able to find the undead……the graveyard. Armed with only a pistol and several grenades, you quickly get yourself lost. Now you must fight your way out of the graveyard or risk meeting the same fate as everyone else.
Fit's pretty well I think. There's a free and a paid version, with the full version offering more levels, upgraded weapons, achievements and awards, endless mode and even more types of zombies. We have a link for trial version after the break, as well a a video where you can see just how cool this one is. Thanks for the heads up Dan!
