Modern humans around the world are randomly pulled into [Dead Space] and forced into a copy of the rules. They must strictly abide by the absolute rules of the copy. Violation = instant erasure.
You can get: points, physical enhancement, rule skills, props, and permissions by clearing the level.
Failure = Team wiped out.
After clearing the 10 ultimate dungeons, you can face the master god of space and choose to destroy the space/become the new master/return to reality.
The truth about space: Higher civilizations use human fear as energy source, rule monsters are transformed dimensional creatures, and violators are failed products eliminated by space.
