Collect the food and water crates to become faster. R to reload and only when ammo is 0. collect ammo crates to get more total ammo and med kits to heal to full health. WASD or arrow keys to move. Space to shoot. you lose food for every step and water every few seconds. The zombies will attack and the guy in the corner will shoot at you every ten seconds. I didn't have enough time to test the whole thing, so if there are any problems tell me in the comments section! Like and fav!
Credits to X-space for teaching me and the USA military for the idea from Conplan8888. New style (not complete) More zombies coming soon! The blue zombies can teleport
