About Sublevel Zero Redux:

Sublevel Zero Redux is a roguelite six-degree-of-freedom shooter set in a universe where reality is falling apart. With your gunship, fight in zero-g through a vast, procedurally generated underground facility to recover the technology you need to escape the many dangers hidden around every corner. Featuring a brand new expansion that adds hours of new content, the action is more intense than ever.


The Redux expansion brings many new features to the game, including a restructured campaign, new enemies, difficulty modes, new starting classes and much more.


Strap on your Oculus Rift or HTC Vive and experience Sublevel Zero in Virtual Reality with an immersive cockpit view and VR-enabled weaponry.


Your gunship is free to fly and rotate in all directions. You can attack from any angle, and so can your enemies. Inspired by classics such as Descent and Forsaken, Sublevel Zero’s retro gravity-defying combat is driven by modern looting and crafting.


No lives. No saves. Fight your way through a different procedurally generated environment every time. Make every shot, every decision count. A wide range of environments stand in your way, from industrial zones to mining caverns. Think on your feet and adapt to each one’s hazards before it’s too late.


Collect a wide range of randomly-generated weapons, upgrades and game-changing items. Craft them together to equip your gunship for your play style. Unlock more items and blueprints as you play and keep those unlocks across playthroughs.
