About This Game

Build the maze. Annihilate the horde.

Horde Lab is a tower defense where YOU decide the path. Place walls anywhere and the horde will always look for an open route: stretch it out, drag it under your towers' fire and watch thousands of enemies crash against your maze.

Thousands of enemies at once

Rivers of enemies, knockback, chain explosions, lightning, fire and vortexes. And when a missile lands on the thickest part of the horde... time stands still.

3 vs 3 online

Team up with two friends (or fill the seats with bots) and take on three other players online through Steam. Everyone raises a base, sends troops that level up and unleashes bosses with abilities. Coordinate purges, cover your allies and tear down the rival bases. With lobbies, team and all chat, and a wins leaderboard.

Every run is different

• A new map every run, with gates that open as you progress.
  
• Cards every wave: choose from common to mythic upgrades and build a different combo every time.
  
• A boss at the end of every wave, with random abilities and auras... and some of them steal your cards.

A 562-upgrade skill tree

Every run earns points for the skill tree: unlock towers, upgrade them and pick unique special abilities. The more you play, the further you get.

AI Generated Content Disclosure

The developers describe how their game uses AI Generated Content like this:

AI tools were used during development to help write the game's code (including the scripts that procedurally generate its sound effects and store art), to compose the soundtrack (melodies and arrangements written with AI assistance, rendered from our own scripts and an MIT-licensed instrument bank) and to translate its text into 10 languages. Game design, balance and visual direction are the developer's own, and all AI-assisted work was reviewed before being included. The game does not generate any AI content while you play.
