I liked the intro a good bit and the story was ok, but I kinda had two gripes:
1) Dialogue voids: there's several times where there's just wing after wing of hostiles coming in for minutes, and no one says anything. Get's a little dull
from personal experience playing the game I would dare to say that combat chatter is merely noticed by the average player, you are pressed to destroy the other fighters not concentrating in the dialogue itself.
I could agree in some way... like adding a small line of dialogue every now and then through combat to make it more.. human like behaviour, so we can agree on that one.
2) Alpha 1 should not have to be precognative: Several campaigns seem to fall into this hole where the only way some mission objectvies could be satisfied is if you specifically kept secondaries in reserve, and started on the objectives before you had been ordered to, or often before you had any reason to start doing them (for instance, going full afterburner to a cruiser and starting to take out it's beams while the cruiser is arguing with your cruiser about surrendering and no one else is fighting).
-examples: The Modair's beam cannon really needs all your rockeyes unloaded into it along with a barrage of tempests, as soon as it warps in. Now disarming the front BC on a fenris/levi is common nature to a lot of us, but psuedo-command should still tell you to do it immediately if you want pilots to do it immediately
-same deal with the deimos's side cannon, swift failure comes in if you don't take that out as soon as the thing warped in
Obviously a fun campaign must make the player work for the glory, that forces us to make alpha a key in every combat... there's no point in starting a mission and not being able to make any difference in the outcome.
I know what you are saying.. not getting good advices in time, but think that command is cut off, the only ones that can give you a hint are the cruisers, but they are already busy in the battle.
here comes in game the cunning of the player, most veteran ones will know by instinct that the first thing to shot down are the main beam turrets, and if you are not a veteran... well we can make a veteran out of you SIR!

don't worry you'll be better informed on the second part... but be carefull, the NTF fights well, these fellows are not dumb.. and will put up a hell of a good fight.
But overall not too bad, and it IS a demo so I can guess that you guys will do some rebalancing eventually
on future missions... yeah, tnks for the feedback btw.
I just get a little uneasy when anything brings back memories of that one campaign I played where the only way to win one mission is if you go full burner towards where the Colossus shows up (essentially from everyone else's perspective you're hauling ass towards empty space for a minute or two), and then with pinpoint precision take out all of it's primary beam cannons in a certain order priority thus gauranteeing the chance for a much smaller capital ship to do serious damage to the Coli. It's missions like THAT that incur jokes that Alpha 1 is a superjuggernaunt in a fighter that may or may not be an omniscient God 
don't recall any mission like that right now but it should have been fun XD
being god is goooood XD
