Ok, thanks everyone, no more help needed. I have plenty.
In answer to the questions about the lava. I liked lava, and one of my friends (who is mainly going to be playing the map) asked for me to try it out, and before anybody comments on the rest of the map, i have already done a whole boatload of stuff to it, so most of the comments you had were already null and void.
For instance, the computers were already fixed in the back room, i made better paths in the sewers, ones you didn't have to jump on. The walkways were made bigger over the lava, the intel was moved back to where it was, but i left the big room like it is so there is now one more entrance, i added lights in lots of places, but there is still a leak somewhere, so the lighting is still messed up.
In other words. im playing the map now with my clan, and they seem to like it.
