Zombies are climbing out of the ground on every continent, and the only thing standing between humanity and total infection is you, a hammer, and quick reflexes.

Whack first, ask questions never World War Whack takes the classic whack-a-mole formula and turns it into a full-blown zombie defense game. Zombies pop up across a world map of continents — click fast, hit hard, and keep the infection from spreading. Let a continent fall too far and it's gone for the rest of the run.

Eight zombies. Zero mercy. Not every zombie plays fair. Runners sprint between spawn points, Teleporters relocate the moment you land a non-lethal hit, Shielded zombies shrug off damage under the right conditions, Spreaders keep the infection ticking up while they're alive, and Motivational zombies buff every other zombie on the map just by existing. Learn their patterns, track every encounter in the Zombiedex, and figure out how to counter each one before the wave count catches up to you.

Build your loadout Every run earns currency to spend between games on active and passive powers — shields, infection cures, slowdowns, damage boosts, and more — plus purely cosmetic hammer skins to swing while you work. Equip up to four active powers going into a run, level them up over time, and find the loadout that keeps you alive longest.

Prove it on the leaderboard Endless mode never really ends — it just gets harder. Weekly leaderboards reset every week, so there's always a fresh shot at the top. Land in the top 100 and you'll earn a permanent reward for your trouble. Chase down achievements, push your best round and combo records, and see how you stack up.

Let chat play too Connect your Twitch account and your stream becomes part of the run. Viewers can vote to spawn extra zombies, mess with spawn rates, force your powers on or off, flip the map, or lock down a continent entirely — for better or worse. Runs played with viewer influence turned on get their own separate leaderboard, so you can prove you survived chat's chaos.

A little something extra Already own Turing Heads (our first game)? Connect the same Steam account and you'll unlock a bonus passive power here automatically — no extra steps, just a thank-you for supporting both games.

Grab your hammer. The zombies aren't going to whack themselves.
