I posted this in wants, but nobody looked, so I made a few revisions and a map, and here it is:

This is a little map idea I came up with - it should combine one-flag CTF with some zero-g action.

Setting: Asteroid Field. At either end is an VSD and MC40. In the middle is a freighter impaled on an asteroid. The map has no gravity, and the fighters/transports are spawned into.

Background: The Imperial Mobquet Transport Revenant, while secretly transporting sensitive cargo (perhaps TIE Advanced plans), underwent a navigational faliure, and exited hyperspace within an asteroid field. Unable to escape, it rammed an asteroid. As all hands went down, a distress signal was sent. The Revenant's encoder was damaged, and the signal was heard by the Rebel Alliance as well as the Empire. The VSD Wolf, and a Rebel MC40, the Lusla, race to the scene. Both sides must try to capture the sensitive cargo before it falls to the enemy.

Forces
Rebel: 1 MC40 (immobile), 12 X-Wings, 6 Y-Wings (2 seater), 2 YT-1300s (8 seater)

Imperial: 1 VSD (immobile), 12 TIE/Fs, 12 TIE/Bs, 2 Sentinel Transports (8 seater)

Goal

Both sides must retrieve the cargo (possibly some sort of barrel, or maybe a datapad) from the inside of the freighter. The freighter has no gravity, so the teams must fly their transports in close, and release troops in Zero-G suits, who must then search the freighter for the cargo. The first one to successfully take the cargo to their capship wins.

Classes

Pilot - Unarmed (since you can't exit fighters anyway). Only pilots can fly fighters.
Spacetrooper/Rebel Commando - assault and support versions. Can only spawn into the transports. Have a limited amount of air in their suits (5 minutes) to prevent camping of the middle base.

Notes

The flag can only be carried in a transport, as you cannot enter the fighters using the E button - only by spawning into them. The flag will be in the form of a pick-up kit, that will respawn in the Revenant as soon as the player is killed. The game is won upon landing the transport inside your command ship's hangar.

This map should promote teamplay, as there are many more fighters than transports - simply flying off in a transport alone will get you killed. Players will need to wait for gunners, and co-ordinate escorts, to prevent being killed by torpedoes launched form bombers. Ideally, the X-Wings should be armed with only lasers for this map (perhaps the rebels are experiencing a torpedo shortage), as otherwise they will take down the Sentinels too easily.
