About S.U.B.

S.U.B. (Secret Underwater Base) is a two-player cooperative secret-agent adventure with 8-bit arcade visuals and audio. You and a friend infiltrate the Evil Doctor’s underwater base to stop his plans.

Infiltrate the base

You use a submarine to reach the base, then navigate its darkness with sonar. You can switch roles and tasks at any time, upgrade and expand your submarine with better gadgets, and watch out for the Evil Doctor’s minions, including robot sharks.

Game modes

The game has two modes, “endless” and “normal,” and a mix of procedurally generated levels to explore. It supports local co-op for two players, and online multiplayer is available through Remote Play Together.
