Sci-fi idle tower defense

Hold the station.
The void never stops.

Command a lone station against an endless tide from the dark. Your guns fire whether you're watching or not — come back to banked resources, push a little further, and unlock the next system.

What's inside

Idle by design. Deep by choice.

The station keeps fighting

Deep offline progress. Close the game, come back hours later to a wall of banked Temporal Essence.

Layered upgrades

Workshop, Research, Void Tech and the Matrix — each one bends your build a different way. Push through sectors for richer rewards.

Anomalies & keystones

Pull, collect and socket build-defining bonuses. Commons stack, rares shift your strategy, void-tier rewrites it.

Tournaments & fleets

Daily tournaments against other commanders, and fleets with shared goals to chase together.

Goals measured in weeks

Wave milestones, station skins to earn and long-tail goals that reward coming back.

Fair free-to-play

The whole game is playable without spending. Optional purchases and rewarded ads only speed things up.

Recover the signal

Anomalies from the deep

28 anomalies across three rarities. Socket the right four and the station becomes something else.
