First: REMEMBER TO DOWNLOAD, AND PRESS THE GREEN FLAG TWICE (so you don't start out fighting like 40 zombies) This is maybe my awesomeist game. No extra health packs or anything, but infinite ammo and no reloading. There are 6 weapons, weapon upgrades, 4 types of enmies, progressing difficulty levels (every 10 kills), up to 45 zombies on the screen at once (it got laggy after that), and 6 bullets on the screen at once. The weapons are (in order of unlocking) Pistol, Uzi, Revolver, Shotgun, Rockets, and Chaingun. All weapons except the Chaingun have a fire rate upgrade. The Chaingun, once unlocked, replaces the Revolver in slot 3. At 150 kills, the maximum amount of zombies are spawnable. At 310 kills, all the weapons and upgrades are unlocked. The controls are W,A,S, and D to move, and the mouse to aim and shoot. Use keys 1,2,3,4, and 5 to switch weapons. See how long you can last and post your score!
