Please read the readme before posting - as it says in the resdme, this is for HALF-LIFE DEATHMATCH SOURCE!!!! not HL2DM. If you run the map in the right game, then it will look right. If you run it in something other than what it was made for, then you will see errors.
You might want to test the map next time before submitting, they is alot of purple and black squared textures in the map. Also they is a model missing as they is 1 of them big ugly red error's. Great map, just needs fixing.
