Finishing Portal in the quickest time imaginable may be rousing, but Valve fans will feel their mouth start to water when this player beats the original Half Life in around 45 minutes, all by using nothing more than that trusty little crowbar. Seriously, Half Life can be a notoriously tough game, not in a frustrating way, more in an exciting, enjoyable way. To beat the entire thing this fast, not even stopping to use a gun in the process, is awe-inspiring. Gamers still hold out hope that Valve will announce Half Life 3 sooner rather than later, but just try watching this without being tempted to go back and play some of the older games in the franchise, if you can pick your jaw up off the floor.
