Purification: Idle Defense

Idle tower defense on PC

Purification: Idle Defense is a PC tower defense and incremental idler about defending a sanctuary from waves of shadow creatures. You position turrets along the defensive line, then strengthen them as you clear stages. Steam leaderboards let you compare defensive milestones with other players, and the wall collects souls and resources while you’re away for you to claim later.

Turrets and relics

Enemies drop relics in different tiers, and each turret has dedicated slots for equipping them. Turret types have different playstyles, while relics can change how weapons behave and interact. Common utility seals sit at one end of the loot range, with Legendary and Mythic artifacts offering changes to weapon behavior.
