ShootUp.io: shoot and win!
You find yourself in Raven City, which is infested by zombies all around, so the only way towards survival is killing them by shooting them down before they can eat you, and be careful of other players at the same time since in a zombie apocalypse, everyone is for themselves.
You can find weapons or items on the ground or by tearing down houses, you can use cars, but the noise attracts attention, and when it comes to cars, don't get stuck with them or run out of oil.
Use the mouse to move, left click to shoot, the right click to place walls for defenses, and hold shift to run. Zombies only spawn on the roads and know that for 100 killed zombies you can get 1 bonus for your character.
It's really that simple and fun, so let's begin right now after which there are plenty more amazing games waiting here for you, try them out!
How to play?
Use the mouse.
