ok well i had posted a HL2 review and I said it was awsome. well this is one basiclly the same thing. but shorter. MUCH shorter. this game will take you only about 6-7 hours to complete. i beat it in one day. but that said, all the game play you know and love it back in this "X-Pack". but now you start witht the GG gun. (the one that is Blue). it is acually i nice way to start off. the end of HL2 left you guesing on wtf was going on. This will to. look, if ya LOVED HL2, then just get this even though its short, its got all the gameplay youi know and love from the HL seriers.
