Pros: Simply THE best game ever created on the 360, or any other platform, period.
Cons: No multiplayer support.
The bottom line: If you haven't bought this game yet, you are missing out on the best benefit of owning the Xbox 360 system.
Simply put, the best game made for the Xbox 360, to date. If you haven't played it, you really owe it to yourself to do so. The graphics are absolutely stunning, and the settings and story line is totally unique from anything else available on the 360 or any other platform -- However, it is not "unique" to the point that you'll feel alienated from the flow of the game play -- in other words, if you like first person shooters, you'll feel right at home with Bioshock. The atmosphere is very creepy -- downright scary in a lot of ways, and the storyline will immerse you in as if you were watching an action/ horror movie, and were actually IN the film. The musical score, voice acting and script are better than any game before it has even hoped to achieve, and make a basically unbelievable story line seem not only believable, but as realistic as any other game has ever been able to achieve. There is no multi player support at all, but the size and length of the single player mode is completely worth the investment of $60, or whatever price you can snag it for. Without spoiling anything, playing the game differently will actually generate alternate endings, so the replayability level in single player mode is relatively high compared to most first person shooter type games. If you are a fan of fps or action games, or if you just simply like a great story. or are a fan of scary movies, you'll love Bioshock. This game has set the gold standard for what all games will attempt to be going forward.
