Its ready, works in single player but needs testing in a campaign. This mission is written totally from scratch and has no code at all from the Taldren Convoy Raid mission.
It draftes 2v2, contains 4 freighters (currently) and 1 Q-ship. To win the mission you must destroy or capture the majority of the freighters (ie more than 50%, so currently that is 3 out of 4 freighters). Since this is a convoy raid, it does not remove AI ships if an enemy human opponent is present (which would be silly in a convoy raid).
It allocates bonus prestige according to Starfleet Battles rule S2.0 Victory Conditions, Commander's Edition (I don't have later editions).
It uses all 27 different map terrain types that can be placed into a D2 map (some of which are quite treachorous, more on this later). It also uses a large map.
It awards medals for PvP combat as well.
Originally I had the attacking team warping into the system at the start of the mission, however DieHard proclaimed he would not use such a mission in a campaign, so I removed that aspect.
If anyone would like to test this mission, please feel free to do so. I may make various minor changes to it, however, by and large it is mostly complete and ready to go at this stage. Anything else I do to it will be largely cosmetic or simple things like adjusting the start positions, maybe change the number of freighters (or possibly make the number random) etc etc for game balance. All of which, of course, requires feedback from players.
For now, you can grab this mission from me on MSN, or PM and I'll email it to you, along with a single player campaign mct file. If someone would be kind enough to set up a test server, that would be much appreciated.
