UNDERTOW: The Abyss

Descend one more floor or return with your haul. Build each run with contracts and relics in a complete premium game with no ads or in-app purchases.

Descend one more floor, or return while you still can.

UNDERTOW is a one-thumb portrait roguelike. Tap to descend into the abyss and collect gems, then swipe up before the danger becomes too great. Only treasure carried safely back to the surface stays in your Vault.

Every descent asks for different choices.

• 24 contracts that raise both reward and risk
• 18 relics to combine during a run
• 4 regions with distinct rules
• 5 guardians you must read and counter
• An Abyss Archive that records contracts, relics, seals, and discoveries

Runs start quickly. Descend with one hand and begin again immediately after a failed attempt. Rewards grow with every floor, but anything still in your haul is lost if you cannot return.

One purchase includes the complete game.

• No ads
• No in-app purchases
• No consumable currency
• Every visual theme and gem style included
• Playable without an internet connection

The abyss remembers how deep you went.
