A year old port, still worth playing on the PS3
Bioshock drops you off in the crazed underwater city of Rapture. In this city gone mad, plasmids(pretty much superpowers) have driven the citizenship insane. Giant hulking monstrosities called Big Daddy protect another experiment gone wrong called little sisters. Little sisters are the collector's of adam, adam is basically the foundation of Rapture. What it does for you in the game is allows you to earn more plasmids, increase health and such.
Your goal in the game, escape this crazy place. A mysterious man named Atlas is guiding you along the way from one area to another. You make small choices in the game, but most of it is linear. The only choice you have really is how to deal with the little sisters. kill them, or save them.
The game isn't "scary" per say, but it is defiantly eerie. From the faces of the splicers(the citizenship), the big daddies attacking you, to the eerie recording tapes you pick up along the way. It'll creep you out.
Lots of PS3 fans will complain that 60 dollars is too much to pay for a year old port. But I find it to be every bit worth it. So if you are interested in a different kinda shooter this year, with a creepy story, check it out.
