About This Demo

This demo features 5 zombie types, 5 automations, 14 mutations, 5 sigils and a region. Play the full game on Nov 16th, 2026!

Build a horde by infesting regions, infecting humans, and most importantly, collecting delicious Braaains...

Tear through the living and collect Brains with an undead army of zombies and little critters marching alongside them.

Each upgrade increases a zombie's damage and health. Every fifth upgrade grants a milestone reward, and every tenth grants two.

Automate brains collection with Rats, Crows, Bats, and Chickens! as your little brain harvesters, then mutate them to quadruple their harvesting yield.

Increase Infestation across 5 regions to unlock the power of Sigils, collectible dark magic that can call upon temporary undead thralls or make your current army even deadlier.

Each Region comes with unique Game Changers and 4 modifiers: 2 good ones and 2 not-so-good ones. Start afresh from a lonely Shambler and grow into a massive brain-eating undead horde.

Desktop Mode is a highly customizable desktop companion where you can watch your horde march across your screen, fight humans, and earn resources. Each type has its own key on your keyboard, letting you assist them in the attack.
