Each part of the world is set up with separate regions, they are all in their own .dae, obj, or fbx but if you want just the full level it's all in Level1Full.dae but some objects might have to be edited due to region overlap, they are not edited in the file itself.

Mostly ripped by Hell Inspector and the concrete texture and skybox are ripped by OggySimpsonsFan333. Models and textures are made by Radical Entertainment.

Crediting OggySimpsonsFan333 is not needed but would be appreciated.
