Idle Mayhem: AFK Tower Defense

Idle tower defense that plays itself: your turret auto-aims and fires while you plan the upgrades. Defend your Server Core from endless waves of rogue AI invaders, then come back to a hoard of offline earnings.

Idle Mayhem is a sci-fi idle tower defense game in crisp neon vector style. You are the last AI Sentinel. The swarm never stops descending, and every wave hits harder than the last. You don't need fast reflexes, just smart strategy: spend your data, unlock new turrets, research upgrades in the lab, and push one wave further than your last run. Play for thirty seconds or for an hour. Either way, your defense keeps growing.
