kudos to the texture artist. but the level design is awefull. boring design,t extures scaled way too big, wrong texture placement, incompetent lightning and so many texturing errors that my eyes hurt...

great tipp: TUTORIALS; TUTORIALS; TUTORIALS

but first scale down the textures, texture not visible surfaces with a texture whose flag is set to none (i set the default texture to none and just dont texture unseen surfaces), scale textures to a MAXIMUM of 0.25 (i reccomend 0.1), set some ambient and it looks so much better...
