RELAY: Reactor Defense

Build a defence, link five weapon types, and read each machine wave before it reaches the reactor. Progress through 36 campaign sectors across six chapters and earn every weapon, research rank, and reactor blueprint. Afterlight adds an endless endurance mode with escalating waves. Optional purchases add fixed workshop credits, a second fabrication bay, or a cosmetic Foundry finish. They never grant XP, victories, campaign completion, or random paid rewards. Play the free campaign offline without an app account. Credit purchases, the Foundry Kit, and purchased-credit recovery require iCloud. Free campaign progress stays on this device. Sound effects only. No music or ads.
