What is Bioshock 2? It's a steampunk-acid trip in a fishbowl. It's Systemshock holding a copy of Atlas Shrugged. Basically you fight zombies, buy crack from vending machines, and bust open little girls in order to get to their candy creme filling. Awesome.
So much more than I was expecting. Eerie, nostalgic, ties you in emotionally... The visual appeal is amazing, and it has so much depth to the backstory if you choose to explore - but you don't miss anything if you don't.
Great sequel to an amazing game, empowering being able to play as a Big Daddy, feel like you can take anything on! More beautiful environments and lots of fun to be had. Mulitplayer is really fun too. Cons: Storyline nowhere near as strong as the original
