It may be short but this is the start of something very special indeed. New enemies, new Alyx, who could ask for more!
The levels range from the citadel, underground parking lots, train stations and the likes but everyone is mapped to perfection with each level posing it's own puzzles and enemies. Again the levels are linear but you never really notice it as there's too much going on. Take some of the puzzles for example, in one level you reach a 3 storey parking lot with antlions pouring out of 3 holes on the ground floor. As Alyx watches your back it's up to you to find something to plug the holes with, but Alyx isn't invinsible and will get killed if you take too long. So it's puzzles on the go if you like, you still have the puzzles of "old" where the action stops while you figure out how to get past the electricified water but it's these new puzzles that really lend a hand in making Episode 1, one the best expansion/episodes I have ever played. People are moaning that it's expensive but take into account that over 3 episodes (15 hours+ of gaming) it's going to cost about £37.50 ($60), about the same price for a regular full priced title, some of which only last 10 hours. Oh I forgot to mention, there is a commentry track that accompanies the game which can be turned on and off. I personally played the game through without it and now I'm going to play it agin with it turned on. Vavle have said that there are 115 nodes which you can activate and listen to. So is Half Life 2: Episode 1 worth the money? Yes I think so. It maybe short but the actual quality and content is superb. If you liked any of the Half Life titles then go and buy this NOW, you won't regret it.
