Star Citizen will either be one of the most phenomenal games ever created, or it'll crater massively under the wait of insatiable expectation. Until the game is released and the verdict passed, there's little for us to do but enjoy the constant flow of development videos, such as this one that gives us an impression of how dogfighting will function.
The video is certainly a healthy length at just over 52 minutes, though seeing as it's a recording of a live stream, there are quite a few sections that aren't that interesting to watch. There also seems to be audio issues, with sound occasionally cutting out for minutes at a time.
If you fast-forward to 12 minutes' in, you'll get past the bulk of the talking and into the gameplay. It starts off with a solo cockpit jaunt, followed by a three-player combat involving lasers, asteroids and explosions (obviously).
One of the more interesting bits begins at the 29-minute mark, where the procedural destruction tech is shown off. The best way to do that, of course, is to blast a fighter with a chaingun turret. I always loved the location damage in games like Klingon Academy, so to see that this stuff has evolved to the point where individual panels can be shot off the hulls of ships is simply awesome.
