It's a shame that it was never finished, but it's good that you guys decided to release the files. I can't even count how many hours of work I've put into this, from models to textures to missions to weapon animations (if it wasn't lost or changed, mission 4 is by yours truly, and it was one hell of a confusing mess but I loved playing it). We've also had some of the greatest people from the modding community putting effort into this, all the way back to Dark, who created the Charon and designed the textures for the Terran Forces ships way back in 2001, I think. Anyone remember him?
There was a time, back when the VBB was still active, when MT was the project to go for groundbreaking stuff in FS2. It all became commonplace, and the project's ambition ended up becoming its downfall. But it was a good effort, and I hope everyone enjoyed working on it, and whoever downloads the released content enjoys it as well.
Edit: Also, check the cutscenes! I loved working on them. I'll see if I still have some unreleased ones at home and post them.
