Zombies Attack Idle

Zombies Attack Idle turns brain hunting into a simple idle strategy where undead units do all the dirty work for you. Instead of fighting as a survivor, the player runs a growing graveyard, sends zombie squads into battle, and tries to wipe out every human on the map. Humans protect their brains and stand as enemies on each level. Locations clear only when the zombies defeat all defenders, and the victory flag is raised over the area.

How to play?

Move the main character with the arrow keys on a keyboard or with the virtual joystick on mobile. Reach the warehouse first. There is a stock of extra brains stored there, and these brains work like currency. Spend brains to upgrade the graveyard and unlock more graves. More graves mean more zombies rising from the ground, so the squad grows with every upgrade. When the undead army is formed, send the horde toward the humans and watch it rush into combat automatically.

Some people on the field carry clubs and other weapons, so an underpowered army often loses the fight. In that case, return to the graveyard, invest more brains into upgrades, and then launch another attack with stronger numbers. Levels progress one after another, and beating them requires balancing spending on new graves and timing the attack command. Jump into this zombie idle game and see how far a brain-fueled graveyard economy can spread across human territory.
