Working Stiffs is a new top down pixel style zombie shooter game from Insane Hero. Apparently, a city office has become a host to a zombie outbreak. You and your co workers now must fight your way through 15 levels of corporate cadavers to reach the helipad on the roof the execute an evacuation.
Control your characters by holding mouse button and dragging it around to make them move around following the mouse pointer. Use WASD to navigate through the level while space is to toggle map view. Zombies will attack you when they see you. You can either run or defend yourselves if you have a weapon. Meanwhile, here is
