This is kind of more of a 'missions and campaigns' kind of topic but I dunno.
I downloaded and played the mission using bp multi. Loaded all but 2 assets (Hellion and HellionFAST or something) :ick: but it worked and I was able to play through it using a recent debug build.
Not bad for what it is. It's a BOE spamfest with shivan forces jumping in all around earth and UEF/GTVA forces reacting. You make decent use of the space, and the warship compbat seems to have some purpose.
If you wanted to improve on it, give the player something to do. As it is now, it is essentially a movie with a Sathanas jumping in and massive warships attacking it far from the player's point of entry. In the mission, I found some random manticores and started fighting them until I was told to jump out. Not too different from your average retail mission, only I did it in a Lao Tze. So give the player a more specific objective, perhaps a transport to defend or a wing of bombers to take out.
Nitpick: The 'defend the station' directive flag turns blue way too soon.
"...and Admiral Byrne has suffered a heart attack." That made me laugh. Maybe i'm sick.
