Descend into the Abyss

Navigate caverns, wrecks, and shifting terrain using radar and instruments alone. Visibility is limited. Hazards appear late. The deeper you go, the more long-lost treasure waits and the harder it gets to leave.

Risk It or Lose It

Make it back to the surface with your haul and keep everything: loot, upgrades, progress. Drown down there and lose everything you brought in. Every dive is a negotiation between what you stand to gain and what you're willing to gamble

Keep the Sub Running

The sub breaks down constantly, at the worst possible moment, for the least forgivable reason. Hull breaches, jammed valves; smoke fills the submarine and water leaks in. The list of things that can go wrong is longer than the list of things working correctly. Patch it, smack it, restart it, and keep moving. It's not much, but it's all you've got.

The Ocean Never Repeats Itself

Procedurally generated levels mean no two dives are the same. There's always something new to discover and always a reason to go back down.

Strange Faces at the Bottom

The Triangle has its own residents. Meet the characters that call the deep home, buy cosmetics, and pry secrets about the abyss out of the ones willing to talk.
