To-Do List for the next version:

General Ideas:
New GUI skin by anX @ N7-Media.com
New Music (possibly by d4n)
"Unavailable" (Black & White) images for maps (in case people don't have the maps installed, but somehow have the tours.ini)
Breifings for all maps (make community do this)
Re-do partyboy song on bridge construction to get rid of gap at end
Co-Op Map (possibly Weapons Cache below)
Use Archibald's Weapons Cache ideas

Specific Map Ideas:
Pipeline Mod Map Changes:
Oil spills and friciton modifier, make custom cube maps for spills
Proper Report-Ins around the map, especially for roof
Somehow get parachutes working with a locking room for defense
