This is amazing..It's the entire hHalf Life 2 game, done in 1hr 35mins. If you've played this, ever, then you'll know that it is definatly not easy. Well worth a download. It's a compilation, with all the members from HL2DQ (half life done quick), so it's not an individual effort. Even if you havn't played the game, you'll still be impressed with the time and effort these guys put in making this video.

Do try it out, and if you like it, go visit them at www.hl2dq.net
