Dropping two mini-campaign ideas of mine - free for the taking:
1st - a Narn campaign set around 2259 - post Centauri Invasion of Narn
WALK IN BETWEEN THE SHADOWSAtmosphere Notes: The Centauri have invaded Narn and those who survived the Centauri onslaugh have to seek shelter at the edges of known space. There the desperate survivors ralley their forces and prepare themselves to retake Narn one day.
Plot Summary:Amongst the surviving ships the Narn destroyer S'Van (a G'Quan - the same as in DoW 3) and the T'Loth cruiser T'Vosh are the only military vessels. While the T'Vosh stays behind the S'Van searches the nearby systems to search for hideout where repairs can be made and the forces be gathered.
But at the edges of known space there are dangers beyond imagination and the Narn awaken one of these - a planet full of ancient mashinery (similar to Epsilon III) in alliance with the Shadows...
Missions:1 - EXILED FROM PARADISE
As one of the last military outposts of the Narn falls into the hands of the Centauri the S'Van and the T'Vosh cover the retreat of the evacuees and than jump via jumpgate/jumpdrives to hyperspace to escape the centauri.
2 - UNCHARTED TERRITORY (atmosphere mission - no fighting just talk)
The Narn have escaped to the edges of the galaxy (hence no planets and just a 0.1 sun) and prepare to go into hiding but they have no place to go to - the S'Van is dispatched to find a suitable place in this uncharted territory
3 - NOT SEARCHING HOME...
The S'Van scouts one system, and the learn that the Centauri are following them. S'Van destroyes Centauri forces to distract the enemy and moves on. (Centauri force should be quite small - couple of Vorchans)
4 - ... BUT A PLACE TO STAY (atmosphere mission, no fighting just talk)
In another system the S'Van finds a perfect planet to stay and to hide - fly around and scan navbouys (to simulate scanning sections of space or the planet)
5 - DEN OF EVIL (stealth mission?)
As the Narn prepare to set up a camp one of the Narn groups on the planet has tigger an ancient signal (and learn about the nature of the planet - but that's not reveal until mission 7) and unknown (shadow) vessels appear at the edge of the planets rings (asteroid fields). Player has to remain hidden from the shadows and has to "count" their ships. (Several battlecarps and fighterwings (maybe some non-cannons?) should make up the shadow forces)
6 - LIGHT AND SHADOW
The Shadows discovered the Narn and are moving in the engage the ships in the orbit (by that time the Narn have left the planet again) - but dispite best efforts the shadows cannot be stopped forever - mission ends with a Red Alert as some new informations comes in. (Shadow attack force should be fighters and maybe some of the small non-cannon craft [use them with caution though] - NO BATTLECRABS, although spotted in the last mission)
7 - ENLIGHTMENT
During the RA briefing the player is briefed on the nature of the planet and that the battlecrabs are all heading for the planet's surface - the Narn belive that they could destroy the mashinary on the planet with a few well placed shots on targets on the surface fired by the S'Van.
Player wings have to cover the S'Van as the destroyer moves into position and fires its beams at a dummy. Once the target is destroyed (after the S'Van has fired 3 or 4 times [event bound firing of that beams]) the Shadows fade away as their is nothing for them to do anymore and the Narn jump away too.
2nd - an EA-campaign set post EMW
CLEANING OUTAtmosphere Notes: The Earth Alliance is just recovering from the war with the Minbari - entire systems have been wasted during the struggle and few Earth Force ships remain to secure peace. Althoug still shocked by the sudden "victory" Earth Force Crews have to pick up their usual duties again...
Plot Summary:The EAS Artemis - a remaing Hyperion - is send out to help securing the remains of the furious battles across EA space - at Tau Ceti they find the debris field of one confrontation hand-picked of the valuable parts (high tech weapons - bough from the Narn) by scavangers. With new orders the Atlas moves on to find those who stole from the debris field.
The thiefs turn out to be a band made up by merchenaries, traitors and raiders... and the Artemis begins to hunt them down one by one...
Missions:1 - GRAVEYARD (atmosphere mission)
The Artemis (and accompanying freighters?) arrives at the Tau Ceti debris site and launches shuttles and bots to find salvageable parts - they learn the debris field has been picked clean
2 - HONEST BUISNESSMENHeaving learned that all salvageable debris has been stolen the Artemis' seeks out the head of a criminel cartel (on his personal liner) who had risen during the EMW but had been left untouched 'cause of the war.
After some "aggressive dimplonacy" (with pulse guns and such

) he gives in that he knows who got the parts and trades in that knowledge against him being arrested.
(hostile force should be a liner and some fighters - like tigers and zephyrs)
3 - THOU SHALL NOT STEAL!The first adress the Artemis is heading is a group of raiders ("just a band of thugs with big guns") -- the raiders refuse to surrender and their ship has to be disabled and boarded to get the parts...
("just a band of thugs with big guns" - zephyrs and raider carrier)
4 - STARFURY CHASEAfter the raiders have been eliminated the mercs fear for their hides and try to hide in a local asteroid field but they are found and eliminated... their part of the prey is siezed by the Artemis as well.
(a couple of fighter wings - mixed between zephyrs, tigers, Auroras Mk1 [RARE!!!] and some rare alien fighters - and freighter somewhere for their part of the salvage)
5 - HUNTING THE HUNTERSEliminating the raiders and the mercs drives the traitors out of hiding - although they never wanted to fight the minbari these are very willing to take on the Artemis as they have their own Hyperion (better guns??).
They don't surrender until their cruiser goes down; and shortly before that they jettison some life pods. Mission ends after they surrendered.
(a Hyperion and Aurora Mk 1s should make up the hostile force)
