Catnip Wars is a 1-4 player co-op tower defense game in which players control Catbots defending a catnip farm from waves of monsters. Turrets, walls, farms, windmills and repair stations are placed freely on a hex grid, and the farm doubles as the economy: catnip fields fund weapons and windmills power turrets. Fourteen monster types attack the farm, ranging from swarming chompers to armored giants and boss Necros. Players can man a heavy BFG turret, revive downed teammates, and progress through a 43-node tech tree across matches. The game includes eleven playable Catbots, 100 achievements and global leaderboards, and can be played solo or online with up to four players.
