it is a so great game i love it so much!i play the multiplayer a lot and its a fun game it is a 14 level game.go to hint and cheats to get cheats.there is a lot of blood but it is so cool!!!!!!its violent/action/bloody/"GUNY"/funny/scary (only in chapter 6 ravenhome)/cool/and finaly (dangerous)??????you'll find out what that means.you'll love this game In Half-Life 2, you once again assume the role of Gordon Freeman, the theoretical physicist and dimension-hopping commando who saved the world from an alien invasion at the end of Half-Life. Or did he? Half-Life 2 starts you off facing the infamous G-Man, the mysterious blue-suited character from the first game. At the end of Half-Life, the G-Man offered you a choice: work for him or die. Since there would be no sequel if you chose the latter, Half-Life 2 assumes you chose the former, and you start the game in a train entering City 17 for your introduction into this new world.City 17 is a run-down urban center that's the equivalent of the Warsaw ghettos during World War II, but instead of Jews being rounded up to live in City 17, it's all the remnants of a defeated humanity. Half-Life 2 takes place an untold number of years after the Black Mesa incident, but it's clear that much has changed. A mysterious enemy known as the Combine has conquered the planet and installed a human puppet government to carry out its rule. Black-clad security forces patrol the streets, while propaganda blares endlessly from omnipresent video screens. If there's one thing that Valve does extremely well, it's capture a sense of atmosphere--this vision of a dystopian police state is chillingly effective. But you won't spend a lot of time soaking in the scene before you're thrust into the struggle to defeat the Combine and free humanity.
