The first 4 missions are like... training levels. The game seriously picks up a couple of missions past that. You don't even have the ability to disengage your alpha limiters until mission 5 or 6 (the one presented in the demo). As for the HUD vector thing? It's useful at certain points in the game, but it's best employed in the campaign during a couple of really awesome sequences where they require you to use it. My biggest gripe is that it was short. But I think there's some major replayability in there, particularly if you get some buddies to fly wingman.
