The game

One farm. Four Catbots. Infinite monsters.

Catnip Wars is a 1–4 player co-op tower defense game. You and your friends are scrappy Catbots — the last line of defense between a precious catnip farm and endless waves of hungry monsters. Build, repair, shoot, and hold the line together, or alone.

The farm is the economy. Catnip fields fund your guns, windmills power your turrets, and every hex you plant is another hex you have to defend. Place turrets, walls, farms, windmills and repair stations anywhere on the grid — your layout is your strategy. Overbuild and you lose it all. Grow catnip too fast and you may attract unwanted attention.

Fourteen monster types push back, from swarming chompers to armored giants and boss Necros that shrug off small-arms fire. Man the BFG when a wave gets ugly, revive teammates who go down, and climb a 43-node tech tree across matches. Eleven playable Catbots, 100 achievements, global leaderboards. One farm. Four Catbots. Infinite monsters.
