To answer some of the questions.
1. I am not sure why it does not load. I am guessing it is a shader issue. Send me some details privately and I will look into it Link.
2. The storyline and design document is not complete I must confess. This will be done shortly and neither the less has enough information to proceed. But i agree it is good to know what is being aimed for before you begin.
3. I will upload models and WADs when people join up.
4. The schedule is for a release around September 07 if possible the aim is to sell the game at a good time of the year.
Cheers,
Static.
