You’re being chased by zombies and other monsters, and there’s an electrified fence keeping you from escaping. Fortunately you have a gun, as well as occasional powerups. Blast those zombies to stay alive! And try to get powerups as often as you can to help boost your odds of surviving. Note: See below game for instructions and tips.
Instructions: Use WASD keys to move around; mouse to aim and fire. Keep an eye on your ammo, because when you run out, it takes a moment to reload. Once you get a little farther into the game, the zombies start shooting at you, so stay on the move. Also, some powerups create big explosions, which might not be a good thing for you if you don’t have much health left. One good strategy is to get all the monsters to chase you, then blast them with a heavy-duty weapon that will kill several of them at once.
