Game Description

You are ECHO-7, a synthetic reconnaissance unit that crash-landed on a barren alien world. Something deep underground pulses a strange signal every 14 seconds — an alien broadcast that was here long before you arrived. Your equipment picks it up, but so do the creatures.

Mine silicon and iron from the planet's surface. Build walls, turrets, and relay towers to extend your signal reception zone. Craft composite materials to unlock stronger defenses. Each night, waves of alien creatures emerge from the darkness — drawn to the electromagnetic noise of your structures, and determined to destroy them.

Beneath the surface lie cave systems hiding Stop Time Crystals and rare resources. But time spent underground is time your defenses go unmanned.

Your power cell has 12 nights of charge. Expand your signal network, explore the caves, and find a way off this rock before the power dies and the darkness closes in.

How far can your signal reach?

Survive for 14 days!
