The first screenshot is the alien hive room. In the background in that window is the ready room. I always thought it would be interesting to be able to see the game from the readyroom... The glass is pretty thick too, so no /stucking.

The second screenshot is another angle of the hive. There is a ladder in the back that takes marines from top to bottom, only the side facing the wall works. I tried to keep people from getting about halfway up and shooting the hive from that...

The third shot is of the large hallway between the rooms. There are pipes and things to keep people from looking all the way through, which would lower FPS. There's also a bridge for no reason, and ladders that go up.

The fourth is another angle of that room. You can see the readyroom again.

Here is the marine spawn. I think I did ok on the driveways that go up and down. There's also ladders to get down too so marines do not have to go all the way around.

The last shot is another angle of the spawn. Theres a little area marines can climb up to near the pipes if they want... I dont know why they would, but the opportunity is there. There's also ladders that go to the very bottom right next to the ramps up.

If anybody wants the zip file, I am going to ask the leader of my clan if it's ok if I link to the zip I posted there. But, you probably do not want it anyway.
One thing I found though, it is a lot of fun to fly around as a celerity lerk, as you can just type +jump in the console, take off from a high spot, and never stop.
