Actually he's got them in a playlist, so that's handy. Thanks for the suggestions. It's amazing how many people don't bother to state the difficulty level they're using, but I think this guy's using Heroic, because that can be seen getting selected in the first video. His playlist description says "Watch me suck at singleplayer Halo", which didn't sound all that encouraging, but he seems to be doing ok from what I've seen (namely, some of level 2). Although, the way he's handling that Ghost, I'm reminded of someone clinging on to a bucking bronco.

Weird seeing all the unusual stuff in recognizable settings. I wouldn't have minded romping around the ring with a Brute Shot at all.
