Crush Depth: U-Boat Simulator

Please note, this is an Early Access game!

Crush Depth: U-Boat Simulator is a world-scale World War II naval simulator with unparalleled depth and realism; the definitive submarine simulation experience. Operate and maintain the U-Boat’s complex machinery, engage enemy against enemy naval, land, and air assets, navigate by the stars, sustain your physical well-being, and enjoy the lighter sides of life on board in the most authentic re-creation of a U-Boat experience ever imagined.

Everything in Crush Depth is the result of thousands of hours of painstaking research based on original construction plans, rare photos, contemporary sources, and the personal experiences of a U-Boat submariner. Developed in consultation with Friedrich Grade, ex chief-engineer of U-96 (the boat famously portrayed in the book 'Das Boot', and the 1981 film by the same name), and by working closely with Blueprint Archive, Bundesarchiv, the Nation Archive (NARA), the Technisches Museum U-995 and many other sources, we've managed to re-create the type VII U-Boat to a never before seen level of depth and realism.



A fully spherical gameworld recreates the horizon and travel times with accurate detail. The entire world is represented by a full bathymetric and heightmap model with 15 arc seconds of fidelity.



A variety of game modes will allow you to engage with the world as you choose. From short, single encounters based on actual historical events, to customizable patrols, to a perpetual PvP/PvE setting in which you can play for days on end and many more. Play cooperatively as one of the members of a crew of up to 18 players, or take complete control of your boat all by yourself.

Our Virtual Museum, built in consultation with a professional architect, offers an in-depth museum experience covering World War II maritime history in exquisite detail. Our curated experience brings history to life with rare photos, archival video footage, original blueprints, and much more.



Player controllable vehicles include PT boats, destroyers, merchants, and even planes.



Intelligent AI ensures NPC units behave in a realistic and historically accurate manner. Units take time to recover from surprise attacks, weather effects sensors and visibility, radio communications can be used to triangulate your location, and more.

This is not just a simulator, this is history come to life.
