What makes Bioshock so great is what made Oblivion great, which is the open-ended well crafted environments that really made you believe your were a part of the game. Bioshock has that in huge quantities. But it also has those tiny details that separate a great game from a memorable one that you'll return to years later.

Remember one of the great things about Doom was the ability to get the enemy to fight each other? You can do that in Bioshock too, and it really makes you feel that the creatures you encounter have life. And if the creatures are not killing each other, they are scavenging, looking for intruders, or generally exploring. Which is what so many FPS AIs lack. This alone makes Bioshock a great title.

The story is also great in a generic type of way. It's 1960 and your plane crashes in the Atlantic Ocean where you find a submarine that takes you to an underwater city inhabitanted by mutants. If you're wondering this mutant/zombie city exploration idea has been done to death, you're right. But what makes a story good is the way you tell it, and Bioshock tells it using gorgeous next-gen graphics and sound. And unlike other FPS, there's enough light in the city to see the graphical detail. The city has a 1920's Art Deco style to everything.

You got the superpowers in this FPS. But this time, you can customize them and change them any time you want. The powers use something call plasmid. It's some genetic material that lets you control gravity, fire, and electronics. Which is real useful considering there's automated turrets all over the place. There's also tonics that enhance your abilities. So there's plenty of ways to customize your character.

The way you get these powers is by taking genetic material from little slave girls who harvest them from dead bodies. But if you take them from the slave girls by force, they die. So you have to "free" the material out of them. You can use either method and it's very disturbing. Although there is a lack of variety in the genetic freaks you meet, each type is well designed and realistic in their behaviour.

The game is about twenty hours long and unfortunately, there is no multiplayer. This kinda makes sense since you're trapped in an underwater city after a plane crash. Although there's no reason why you had to be the only one on the plane. So you can replay the game on a different difficulty and use different methods of killing your enemies. We're taking off points for no multiplayer since this is the 360 and multiplayer should be available in a 360 FPS.
