First of all sorry if you read the tags there are no giant ant eaters in this game :/
Anyway if you do not have this game, or Bioshock one for that matter, you need to go shoot yourself right now because your life is clearly incomplete. Personally I thought the Bioshock story was pretty interesting, although Bioshock 2's story is so-so. Seriously this game is great. YOU HAVE GOD DAMN SUPER POWERS FIGHTING PEOPLE FROM THE 1960'S UNDERWATER it doesn't get any better than that.
