Keep Zombie Away is a thrilling survival game that drops you in the middle of a world after the end of the world and is full of scary zombies.
It's clear what you need to do: get to the safe house, get out of the chaos, and defend yourself against the monster attack. As the levels get harder, you'll need to think strategically to stay alive during the zombie apocalypse.
A countdown starts as soon as the alarm goes off. Find a room that isn't being used and go into the hall to hide. You should try to get a college room before other players take them all. A locked room is off-limits. You're also doomed if you're still stuck in the tunnels when the zombie shows up.
As the game gets harder, you need to be smart about how you improve the protection of your safe house. Give priority to the improvements that will give you a tactical edge against the endless zombies.
Have fun and good luck!
