its more than a game its an interactive experience with an excellent story PLEASE READ ON
the story starts off as you a man named Jack who was a passenger on a plane then it mysteriously crashes in the ocean coincidently next to a lighthouse that will take you down to a city called Rapture which is an underwater city made by a man named Andrew Ryan (not the Bulldogs player from NRL) who has made this city where scientists will be able to work on their research on advancing human capabilities where no petty morals or religion will not bother them, then once you get into the city itself you realise the dream has REALLY F**ked up, the story is told fantastically with big plot twists and a creepy setting.
Bioshock is one of those games that make you adapt to your environment, your average enemies are these Splicers which are mutated survivors that have abused this drug called ADAM which can give you supernatural powers, Splicers come in four classes the aversge ones that attack you and don't do much, Leadhead Splicers are like the normal ones only they carry a tommy gun, Nitro Splicers are also like normal ones only they throw grenades, but the last ones are the Houdini Splicers which can teleport to other places in a red cloud of smoke and can command security and other things to fight for it. other than them there are these things called Big Daddies and they serve as the boss fights there are mant different types off them but there is not much difference between them the big difference between them is that some of them have little sisters now you don't actually have to fight big daddies but if they have a little sister you must take out that big daddy and then either Harvest or Rescue that little sister and thats where moral choices come in if you Rescue all the little sisters in the game you get the good ending, if you rescue half and harvest the other half you get an average ending and if you Harvest all off then you get the crap ending you can play it the way you want to like if you harvest them you get heaps of ADAM but when you finish you get the crap ending where if you save them you get less ADAM but you get the good ending.
speaking of adapting to environment you can use ADAM to buy PLASMIDS and TONICS which give you supernatural powers like shoting electricity, fire, ice, bees and more and even use telekinesis and they are awesome and ofcourse you get standard weapons like at the start you receieve a wrench which is your melee weapon then you get a revolver pistol then a tommy gun, then a shotgun then later in the game you get things like a grenade launcher and a crossbow each have three different types of ammo from regular ammo then thing like trap darts and armour piercing rounds to ammo like heavy bullets anti personnel rounds and guided rockets, which is great.
the bad thing is by the end guns get pretty useless so you must rely on Plasmids to do it, that the game is pretty short and that the game is so about trying to survive that it is very easy for example on hard youll only die a couple of times and on easy you won't die once unless you make a mistake like blow all your money on bullets and not first aid kits and stuff like that but other than that this game will go down as one of the biggest games of the decade and it is a must play, high hopes for BIOSHOCK INFINITE 9.5/10
