Echo is an artificial consciousness. Endlessly recurring, endlessly rebuilt.
Deep in the desert stands the Echo Core, the only thing holding the dimensional rifts in check. When the rifts tear open, the swarm pours through.
Place turrets, rig gas barrels for chain explosions, hold the line through sandstorms and bioluminescent nights, and push further than the last Echo ever did. Alone or with a friend in online co-op.
Survive escalating waves of dimensional entities and level up your skills as you go. No checkpoints: every wave pushes harder, every run pushes you further.
Up to 500 enemies on screen at once. The desert does not send scouts. It sends a tide.
Deploy and upgrade turrets, place explosive gas barrels and trigger chain reactions that wipe out whole packs.
Team up through Steam and defend the Core together. Two Echoes, twice the firepower.
Switch between FPS and TPS at any moment. Pick the view that fits the fight.
Dynamic sandstorms, day and night cycles, and rifts that open without warning reshape every battle.
23 achievements, plus Steam leaderboards for Furthest Wave and High Score.
