@necros, I am really glad you are working on that map again, it has a lot of potential and some really cool concepts with interactive items and the best boss fight I have seen in Quake!
The vertical elements you have added will make it feel more fun for combat. I would suggest joining the stairs in the middle so you create more floor space for fights and break up the mountain of steps.
