Houston, we have a zombie problem

Lose a run. Keep your Wisdom. Come back stronger.

Houston, we have a zombie problem is a roguelite Tower Defense where every run brings you closer to victory. Build your defenses along forking roads, combine towers, pick power-ups, and hold back ever more dangerous enemies.

Even if your defenses fall, you don't start from zero. Earn Wisdom, unlock permanent upgrades and new towers, and grow stronger with every attempt.

Features

• Build your defense your way. Place archer towers, cannons, barracks, fire towers, ballistae, and more. Use forks and chokepoints to build an effective line of defense.

• Change your strategy on the fly. Choose one of four power-up cards: boost tower damage, upgrade your soldiers, and reduce building costs. Every choice shapes your current run.

• Grow stronger after every defeat. Earn Wisdom and invest it in six branches of permanent upgrades: Treasury, Marksmen, Engineers, Garrison, Kingdom, and Wonders. Gain bonuses and unlock new towers.

• Use powerful abilities. Call down a Meteor on a horde of enemies or summon Reinforcements when your defense is on the verge of breaking.

• Control the flow of battle. Study the composition of the next wave, call enemies early for extra gold, and speed the game up to x3 when you're ready for a bigger challenge.

• Experiment without limits. Changed your mind about your strategy? Refund spent upgrades with one click and rebuild your defense around a new plan.

From green forests to snowy tundra

Fight your way to victory across colorful cartoon locations with winding roads, lakes, forests, and snowy expanses. Each map presents new tactical challenges: pick your tower spots, plan your timing, and prepare for the waves ahead.

Goblins, ghosts, axe-wielding brutes, and horned dark knights won't wait for you to finish building.

Build. Upgrade. Hold the line. And next time, go even further!
