Overview

What'Sub plunges 1–4 players into the mysterious depths of the Bermuda Triangle for a cooperative extraction adventure. Piloting a weathered submarine, players will descend into a procedurally generated world filled with caverns, shipwrecks, and perilous terrain. The core gameplay loop revolves around venturing deeper into "The Well" to uncover long-lost treasures, but the increasing difficulty and limited visibility make every dive a high-stakes gamble.

Highlights

  • Cooperative Extraction Diving: Team up with up to three friends to crew a submarine and extract valuable loot from dangerous underwater environments.
  • Procedural Generation: Explore ever-changing caverns, wrecks, and treacherous terrain, ensuring each dive presents a unique challenge.
  • Risk vs. Reward: Successfully return to the surface with your haul to keep loot, upgrades, and progress; failure means losing everything brought into the depths.
