Gears of War 2: Cue Angst-Ridden Track and Epic Visuals.

While HALO 3 still feels like the gold standard for video game trailers, Gears of War 2 doesn't hurt the cause here with the trailer for Last Day. Just take one part contemplative hero, one part hip track (How It Ends by Devotchka) and mix with YouTube for a week. Result? Well, the internetz don't lie. Just ask captawesome014 in the comments there:

"im a hardcore gears fan, this trailer is epic, i mean how would u feel if u thought u were going to surly die underground and it is ur last day above ground?"

Sounds like a hit to me.
