About this game

Descend into the Grand Deep as an experimental diving machine sent by the Adventurer's Guild to plunder the sunken remnants of fallen civilizations. Surviving the abyss requires carving through swarms of underwater opposition armed with bubbles, bullets, and salvaged junk.

Play unfolds as a twin-stick bullet hell roguelike across three distinct underwater regions, each presenting its own hazards, obstacles, and enemy variants. Progression hinges on selecting and combining more than sixty bizarre artifacts to shape your build, granting abilities like dropping crushing anchors on targets, growing eyes behind your skull, triggering percentage damage boosts, or summoning eel gods to clear entire rooms.

Each descent tests your loadout against over twenty standard enemy types and six demanding bosses as the opposition becomes steadily more erratic the deeper you plunge.
