Take off the triggerhurt in the staircase, this includes taking away hp/armor stations.
No secret rooms.
Less laggy map ._.
If you do these your map will be fine.
Update 9/2/11, I have edited the map and I made the map less laggy. I also extended the blocked off section to make things a little more interesting. Here are other map details:
Blocked off noob trap with a combine force field,
Fixed many Textures,
Deleted many secrets,
Deleted Ballsockets and physics bridge in the bottom of descent, (Cause of lag)
Extended Blocked off Section with a stairwell and many other things.
More things will be added today, possibly releasing the map during the afternoon or evening, if not tomorrow.
