My second WAD- looking for a tester

http://www.mediafire.com/?al2xl9yo7ace616

I'm looking for someone to test my new Doom WAD. The general goal I had in mind was to make it a tech wad based on the UAC facility base. I wanted it to be old school but with some new textures for effect (such as buttons and lighting). I also wanted it to get darker as it went on. It's Zdoom compatible- thank you.

Looking for problems or suggestions for it.

anyone??

There are missing textures everywhere but other than that it looks ok

It requires a texture pack:

Edit: Still missing textures.
