That was fun
I've adjusted my FOV and I was playing on easy cause a narrow FOV makes things harder but I found the mission perfectly balanced
First time I failed the mission cause the shuttle was destroyed but the second time I passed it
There still are a few minor issues with the mission though.
1) There were a couple of messages out of place still. For instance the G'tok mentions that there is only one thing left to do only after it has started shooting.
2) AWOL Debriefing. Haven't you learned to check by now?
The solution you've instituted doesn't actually work yet. It does prevent the G'tok jumping out early but if you press Alt-J at the start of the mission then play to the end you'll find that it doesn't actually jump out (I haven't actually tested that but I looked at your FREDding and I can't see any reason why it would jump out).
The reason for this is because you've used and-in-sequence to prevent the G'Tok jumping out. That's a reasonable use of it but if the player presses Alt-J any time before the "DIR - jump A" event triggers then the game will read key-pressed as being true first (preventing the G'tok from ever leaving).
The solution is actually quite simple. In the "DIR - jump A" event change the do-nothing into key-reset>>Alt-J (You may also need to change the and-in-sequence to AND because Key-Reset is an exceedingly bug-filled SEXP and I never tested it with and-in-sequence so I have no idea what would happen).
3) The reason why I tend to come down on the AWOL bug is because it's actually a little hard to get the form up event to trigger. You've requested that the player gets 100m from the G'tok which might be a little too close. I can't remember if distances are calculated from the centre of a model or from its bounding box but either way some experimentation might be worth doing (changing it to 200m would probably be enough though).
4) Not a complaint. I believe in giving praise where it's due so I always mention thing I saw that were well done. I never noticed it the first time but kudos to you for using alternative wing names for the Narn fighters.
I'm sure that you're not the only one doing so but that is the first time I've seen anyone apart from myself using that feature and it's twice as good to see it being done by someone in the FA
