I'm working on a DOS Build 3D Engine game called Shaw's Nightmare.
Story: Shaw was listening to music and reading a book when he suddenly fell asleep, while he was dreaming his headphones started picking up strange: static, explosions, dogs barking, bones cracking and finally silence. Then a big hole began to form on the floor and Shaw fell in, entering a dangerous world he never knew.
Things aren't looking too good. He seemed to be lost. Then one boy came preparing to shoot him but Shaw found a nearby dagger and stabbed him with it and took his weapon. Then Shaw heard some alerting noises. They know he's here. There's no turning back.
