Lost in the Mist is boring at its best. Let's keep to its best.
I understand that you've made a decision to keep Kappa 3 silent, but the entire wing has also lost their voice. Communications are breaking down and Kappa just completely ignores the problem, flying past without as much as an input. This is made even more glaring when you fly for a minute and a half in awkward silence. I don't expect voice acting, but *something* would be great so it doesn't feel so lifelessly dull. When Pisces wing showed up, in the middle of the dogfight I realize my fellow wingmen were not assisting at all, resulting in Kappa 1's death. On my second playthrough (will explain later why I played this through a second time) is when Kappa assisted me; I was about 10k+m away by the Aquitaine curious to see what happened. Nothing did. They reached their waypoint and waited around, and Pisces wing didn't show up until I closed distance. Then and ONLY then did Kappa wing actually assisted with no casualities; because whatever Waypoint you had going prevented them from such. After the Dogfight, there was a slap black screen that made me think my PC crashed.
It's called 'fade to black', not 'slapped black on screen', mate.
The second half is where problems start to arise. "Escape" means nothing to me, at all. There's no waypoint, no objective marker, just "escape" until I flew adrift for a couple minutes until yet another black screen. I get the FS2 dialogue and...nothing happens. The screen remains black, I'm pretty sure I hear Shivan fighters, but it doesn't end.
Also was there a reason to be able to call in the support ship for both halves? I assumed the second one I was completely on my own.
All in all, if I had to give this a numbered review, it'd be low. Things feel slapped on without much context and this extends to the briefing where you're ordered to follow Zeta wing. The campaign virtually doesn't end and overall it just feels like a wasted execution of a decent idea. Some more context, polish and something to actually interest the player outside of two dogfights and an escape with no escape plan and this would've been worth the 10 minutes.
