Okay, I was playing some sort of test mission, and there were a bunch of enemy ships jumping in, basically Shivan ships (some of them looked really cool, they would be awesome for ingame mods if I could actually draw well enough to sketch them), anyway I forget what kind of ship I was in but I kept trying to run away from the huge shivan capships but I could never get far enough (I could dodge their shots pretty easily, though, for some reason they were only using slightly faster versions of blob turrets but no flak, missiles, or anti fighter beams), anyway afterwards this huge Shivan capship jumped it that looked sort of like a massively upscaled Lucifer (about twice as long as a Sathanas), and it was practically on top of me.
For some reason I decided to try a head - on attack and after I got past its turrets there was a large opening in the front that I could fly through, there were several fighters (basilisks) inside that I had to fight but then the opening continued into a corridor inside the ship. There were robots from Descent 3 (I distinctly remember one of the "Tubbs" bots attacking me) but since the ship itself was moving the entire interior was moving and it was a bit disorienting. I remembered reading that the freespace AI tends to crash into things in interior spaces so I hoped that would disorient them too, but it didn't really seem to.
Eventually the ship came to a stop so it was easier to navigate, but then Borg drones appeared (apparently the Borg had allied with the Shivans), and I had to keep using different weapons (like mega missiles from descent) to kill them, so when I tried to leave the ship I found that there was a forcefield blocking the entrance, so I went back and the Borg Queen attacked me, but I killed her and the forcefield went down, so I escaped from the ship but its turrets were still active and there were still a lot of fighters chasing me, while in the background there was a huge battle between allied ships and all of the combined Borg/Shivan fleet.
That's pretty much all I remember
