About the game
Cat 3 blends roguelite structure with match-3 mechanics, tasking players with lining up alien cats to blast through swarms of cosmic invaders. Each run starts with picking a hero, and as you play you gather relics and layer stacking upgrades on top of one another. It falls under casual, indie, and strategy, and was developed and published by adoptedmouse in 2026.
