Idle Zombie Shelter: Build and Battle for Android

At the bottom of the playing field there is a wall with a cannon, which symbolizes shelter in the world of the zombie apocalypse. The wall is attacked by dense hordes of all kinds of zombies and the player's task is to shoot them before they reach his cannon.

There is an endless supply of ammo, and the cannons can be upgraded as you play. You can also go inside the shelter between the levels and hire soldier - assistants who stand on the wall next to the player's gun and shoot from their weapons. Their weapons can be changed by getting new ones in the shelter. Money for this can be obtained as a reward for completed levels.
