Well first of Yahtzee this big daddy doesn't have fluorescent lights, his helmet just sort a looks like bomberman's head.
But besides that I liked some of the few changes (Mini games are better, Big Sisters add an extra hurdle to overcome besides the Big Daddy and Plasmids can now charge up for beam attacks, Flame ON!) but don't think I'm praising Bioshock 2, god no this was one of the few reviews I almost completely agreed with.
Bioshock 2 is bad in comparison to it's predecessor. Allot of things simply don't make sense (I also noticed the eating through the helmet thing), are uninteresting or are never explained.
Bioshock 2 would have been allot better if you didn't start AS a Big Daddy Prototype but as the original test subject: Jonny. 2-3 days ahead of him turning in a big Daddy, you could have seen Rapture all sparkling and new, seen it's downfall, partake in the revolts or go rob some banks and THAN have fought Crazy Psychiatrist woman. Would have made the first half of the game enjoyable.
Besides that Rapture all leaky doesn't have the same feel as it first did. It was a new world seen from an outsiders view, here we play a BD which is one of Raptures inhabitant which takes a bit away from the atmosphere and awe. Like I already said seeing the Fall of Rapture would have helped to usher back in that feeling of awe.
I found about 6 audiotapes going on about Jonny Topside (You, the player before turning into BD) a lone sailor who managed to get to Rapture using only a submarine and a pile of Luck and basically turned into Raptures hero, it's beacon from the surface shining hope.
Now that is a good hero character, he is daring, charismatic, has a VOICE and personality we would all be willing to get behind.
But maybe they saved that for Bioshock 3. But still if I hadn't run into a 25$ Bioshock 2 copy I would have probably let it slip for AC2 and many other games draining my wallet.
