As the other 2 bioshock games my mind was blown by this game, especially the ending in which every bioshock game has a twist that screws your mind. Now to talk about gameplay, controlling the to weapon types, guns and plasmids (or vigors as they are called in this game) is much better than the other 2, melee has also reached a new stage, instead of it being a equipped weapon like before you swing your weapon at the push of the Y button, and also ,unlike every other bioshock game, you can aim down the sights for a more stable weapon control, sadly though they changed the weapon system to you can only carry 2 at a time and made everything really expensive unless you dont die alot. Theres also a item feature in which occasionally you'll find clothing pieces that give you permante bonuses, like fire punches, or for one kill your weapon damage goes up for 15 seconds. I also want to say the A.I. partner, Elizabeth, is by far my most favorite A.I. in a video game, as soon as i run low on ammo, if its available, she tosses me ammo, when i run low of vigor energy, she tosses me salts (equivalent to EVE hypos). Other than the story line (amazing btw), A.I., and weapon usage, the other thing i looked for was game difficulty, and i can tell you this game has ALOT of it, the game is even made more difficult with the fact that you cant carry around med-kits or salts in a reserve like the other bioshock games, many catagory of enemies, and that everytime you die you lose a good deal of money, and if you choose to play on hard mode or 1999 mode expect to die a number of times and being forced to stay behind every bit of cover available to you. This game has definitely made it to my list of all time favorite games, the Bioshock series again has shown me an amazing time and i can't wait to play again.
