This game is one of those where you have to see it for yourself. Bioshock is a game where you actually can play the game the way that you want.
There is a lot of weapons in this game, most of you already know about the pistol and tommy gun, but what about power weapons like the exploding crossbow, to the chemical thrower. These weapons are fun to use, but the game makes you earn them, unlike other FPS, that give them to you.
Another feature is the plasmids. While you may not think much about them first, you'll soon figure out that you need to use them to survive. The most useful plasmids are actually the offensive ones, so i'm just going to say that winter blast 3, with a combo of explosives = own. You can destory the highest ranking big daddy, if you are lucky enough.
So enough about the weapons, let's talk about the length of the game, since this is only SP, you must be wondering how good it is. Well, the length is great, if you only decide to blast through the main story, there still is a lot to do.
There is a small con in the gameplay, which is a hacking puzzle, but you can actually skip these by using autohack tools, or buying out the hack. However, you can get some achievements by hacking quite a few times, so you might want to.
This game also deals with your thoughts, and emotions like few other games I've played before. You can either save a little girl, or kill her to get more adam. If you save 3 you get a gift that has rare stuff. Repeat this for actually awesome stuff.
I would recommend this to you if you don't have Xbox Live even, this is a game for someone that doesn't care for it, since it is only SP.
Overall I give it a 5/5
