Definitely one of the top choices of games for the Xbox 360...This might go down as a future Xbox 360 classic gem later.
You start off as you crash into this underwater huge Atlantis type of city named Rapture and you start off getting to know the game physics and then you will eventually reach a place where you get your first plasmid...now the plasmids are one of the best things you can do on this game...pretty much your left hand you can do sort of magical stuff such as shoot out electricity, fire, and also you can learn the telekinesis, which you have to use for a mission, which is really cool.
The graphics in this game are just unbelievable...If you really enjoyed Gears of War and thought the graphics were unbeatable?? WRONG, Bioshock has EVEN BETTER graphics than Gears...I couldnt believe it for myself but it really does...everything looks neat and it makes it even more enjoyable to just explore the world
Sound is really great...it would just be like if you were watching a movie that would go on this kinda type of story line.
Also another thing I gotta agree with the reviewer of GS who reviewed this game, some people may think the combat may not be all that like say Call of Duty 4 or such but those people who think would just miss the point of the game...its not just about the combat, its a really deep game that you just gotta explore and solve a bit of puzzles.
So overall, its just a game that you just MUST own...when you see it in one perspective, it will be a decent game but when you put it all together, its just GREAT...just give this game a try and you wont be disappointed!
