Lumen Keeper

Your light depends on the enemies you take down.

Build the defenses you’ll fight alongside. Take control of a small robot and face the swarm in an action roguelite blending tower defense and base building.

Aim, fire and dodge alongside your turrets. Protect the reactor and bring Lumen from fallen enemies back to it to keep the light on.

If the reserve runs dry, your safe ground shrinks, exposing your buildings to corrosive fog. In a crisis, you'll sometimes have to enter the fog to recover Lumen.

Place turrets, cover vulnerable approaches, and extend your network with relays. Day has no timer: prepare your defenses at your own pace, then start the night when you're ready to put them to the test.

Between nights, choose your blueprints and upgrades from the cards on offer. Strengthen your base and combine doctrine effects to adapt your strategy to the coming assaults.

Even after defeat, invest the resources earned over the nights in permanent upgrades for your robot and defenses. Return stronger to hold out longer against the swarm.
