"The United Allied Cooperative (UAC) has developed a new secret weapon, the BFG9000. Your assignment is to break into their headquarters and get it. We will place you at the entrance. Just go in, get it and come back out (getting the BFG will lower a sector at the entrance, allowing you to exit the level from there). We don't know the layout of the building, but we do know that there is an armoury behind a red key door, and that the red key is kept in the computer room which itself is behind a yellow key door. This is important as we suspect that you may encounter some resistance, and the only offensive equipment we can provide you with is a lowly pistol. Good luck."

New level from scratch
hours, days, weeks, months (a long time)
DEU and BSP, until they failed. There seems to be a limit to the size of the level. BSP11X did not help, and I've had to scale this level back. IDBSP seemed to hang every time I tried it.
One texture goes dark when you get close. Everything else seems to work properly. There's a lot of stuff so you'll need a fast machine (486 minimum).
