A zombie apocalypse turns America and the world into ruins. Many people around the world tried to fight the zombies but there were too many of them. luckly for your case, the city has built walls and forts to ward off zombies. Despite this, nobody depended on the walls for protection.

The goal of the game is to shoot oncoming hoards of zombies that come to attack your fort. If the zombies manage to hit the wall 100 times, the fort will collapse and the game is over. The zombies now have an advantage to infect and take over your city and state.

Throw grenades with G and shoot with M1.

Helpful TIPS!!:
-DON'T EVER AIM FOR THE HEAD!!!! You will miss 60% of your shots to an enemy. It's best to aim for a body shot. Right now, a companion can only achieve "head-shots" with any kind of rifle.
-When throwing grenades, put the cross-hair closer to your player. Your player is very strong and can throw grenades extremely far.
-Use the environment to help you.
-Always buy repairs for your fort!
-Don't make stupid decisions. It's going to matter in this game.
-A machine gun is the only thing you need!
