Half-Life 2: Episode One came out last week. I just finished playing it and it\’s awesome. Lots of great set pieces and battles. Valve are the masters of level design. It\’s as if they took all the best parts of Half-Life 2, cut out the slow parts, and released a lean, mean action game. For the add-on Valve went the episodic route, so episode one was pretty short. I think it was worth it though. I loved Half-Life 2 and this was a great addition.
