I think it was filmed in H2, though it could have been H1 (H3 was a distant speck on the horizon at the time). It was a kind of map montage where the player played through the maps getting points until he finally won the game with 25 kills to zero deaths. It had really badass transitions that were so well done you couldn't even tell the map had changed until you blinked and realised things weren't the same.
I'm sure a few of your oldschool members will know the one I'm talking about. I think it came out some time in 2007?
Any help (names, authors, engine, etc) would be appreciated.
UPDATE:
Found what I was looking for (thanks to phobias at H2V).
