Stupid-Zombies

These silly zombies are again, and you might be humanity’s final hope to maintain them brainless. However beware, ammo is proscribed so you’ll have to get artful and use the straight bullets, grenades, split- and buckshots in the best method attainable to outlive the 960 ranges. One man, one shotgun and many silly zombies.
It’s simply you vs zombies so be sure to cease the infinite offended hordes earlier than you run out of bullets
