When I heard this game finally came out I HAD to play it and see how it was. And apparently, I loved how they improved upon it. Although sadly, I don't like the comments around the net on how people think about it. If you know nothing about Bioshock, it's a game made by 2K Games, the same people who made Borderlands. People think this is a "scary" game, but it's all on your experience on scary movies. I myself, have been exposed to scary movie since I has a little one, so it wasn't much, so I thought this was great.
The story setting is COMPLETELY different from the 1st Bioshock game. You are a "Big Daddy." A kind of enemy from back in the 1st game who takes awhile to kill that is accompanied by a "Little Sister" little girls supplied with ADAM (game talks about wth that is...) Anyways you are the oldest Big Daddy in the game someone named Delta Herr, aka "Subject Delta." In the beginning of the game you follow your little sister around, Eleanor. Until these guys, splicers, take her and knock you unconscious. Then some lady tells you Eleanor is not yours anymore and orders you to kills yourself. Somehow you live and your quest starts there...
Bioshock 2 has a LOT more weapons and weapon upgrades from the last one. Not to mention new monsters like the "Big Sister." (Hate that bitch.) Also, unlike the 1st Bioshock, there's more endings. 4 of them. 2 neural good/bad and 2 very good/bad endings. It all depends on your choices on who you kill and whether you take ADAM from the sisters or not. My tip for the game: ALWAYS use the camera. Also I gotta say this even if it is a minor spoiler: older Eleanor is hot and badass. xD; *cough* AAAAAnyways, good game and gameplay only peeve about it is the mouse control. I give the game a 8/10
