UNDERTOW: The Abyss

Descend. Then decide how much you dare to keep.

"The abyss remembers how deep you went."

A one-thumb push-your-luck roguelike. Tap to descend and collect gems, swipe up before the danger becomes too great. Only what you carry back stays in your Vault. One purchase, no ads, no in-app purchases. No account, plays offline.

Inside the abyss

A short, sharp loop about greed and nerve. One purchase includes the whole game.

One floor deeper, or return alive

Tap to descend into the abyss and collect gems. Swipe up before the danger becomes too great. Only treasure carried safely back to the surface stays in your Vault.

Something remembers

In the dark, something tracks how far you have gone. Every run is a gamble against what waits below.

24 contracts, 18 relics

Contracts raise both reward and risk. Relics combine during a run. Four regions with distinct rules and five guardians you must read and counter.

One purchase, everything included

No ads. No in-app purchases. No consumable currency. Every visual theme and gem style is part of the game you bought.

Offline, no account

Play as a guest with no login. The game runs offline; a connection is only used for the optional Game Center leaderboard.

The Vault and the Abyss Archive

If you are signed in to Game Center, your best banked depth goes to the leaderboard. The Archive records contracts, relics, seals, and discoveries.
