What'Sub Demo

About this game

What’SUB is an online co-op action game where you and your crew operate a failing submarine, navigate hostile depths, and extract the highly valuable spice; coffee. The sub is unreliable, the pressure never lifts, and coffee delivery does not stop because systems fail.

What’s in the DEMO pot:

  • Experience the life of a pirate under the sea: Take a swig from the coffee mug, learn to steer the submarine while water is up to your knees, and try completing the mission!

  • Single Mission Type: Experience a standard "Voyage" mission, with a few different maps to test your navigation while traversing through obstacles!

  • 4-Player Co-op: Bring your friends along a great adventure and find out how your crew best manage under pressure!

  • Character selection: Be a man, a woman, or even a fish!

  • Emotes: Be the best pirate anyone has ever seen, and make the best emotes at the worst times!

What’s brewing for the Full Release:

  • Different mission types and sub missions

  • Different environments: Icy caves, dark volcanic depths, overgrown corals on shallow waters!

  • Pirate Progression: Deep character and sub-customization. Earn loot and reputation over time. Become the coolest pirate you can imagine!

  • More sea life and sea 'things': Cute puffer fish, living kelp forests, eerie naval mines, speeding sailfish, and more to make the ocean exciting!

  • And much more!
