About What'Sub

What'Sub - about the 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.

All pirates on deck! 

A single submarine. Multiple stations. Helm, engines, pumps, radar, repairs, and coffee storage all demand attention at the same time. Communication is constant and incomplete. Crews succeed by distributing focus, reacting to breakdowns, and compensating when something goes wrong faster than it can be fixed. 


Keep the Sub Running! 

The hull leaks. Valves jam. Power cuts out. Systems fail under stress and rarely in isolation. Patch breaches, reroute power, restart machinery, and keep the sub functional long enough to finish the delivery. Ignored problems compound. Delays turn small failures into cascading disasters.

 

Navigate the Depths!

Use radar and instruments to chart a path through caverns, wrecks, and shifting terrain. Visibility is limited. Hazards appear late. Steering, speed, and positioning all affect what the crew must handle inside the submarine. Navigation errors increase internal strain as much as external danger. 


Extract the "Black Gold" 

Every mission is a desperate scramble for the bean. Extract coffee from natural deposits, rupture submerged pipelines, or take it by force from rival vessels. The longer you stay, the more the environment pushes back. Get the cargo, fill the hold, and get out... or die trying to reach that perfect roast! 



Features:
• Online co op for up to four players! 
• Proximity voice chat inside the submarine! 
• Interdependent submarine systems and repairs! 
• Radar based navigation across the ocean floor! 
• Different types of submarine missions! 
• Character customization!
