Seriously. I had the most fun on this map above all else. Sidewinder is definitely a close second, but I rarely had the opportunity to play with more than eight people to make that map really worth it. But yeah, Damnation. It was the best!
Halo Anniversary will be getting about a half dozen remade maps based on the original Halo: CE maps and this new video shows off Damnation's fancy new coat of paint. We also have a look at Beaver Creek below, but that map was boring so whatever.
