Well take my advice don't waste your money , it gave you the fell of wetness (because you under the sea)and emptiness .
no related elements from the BioShock 1 , in the first one there is a passenger whom his airplane crashed done in to the ocean , and find his way in water to place called the rapture , then the story begins to fight his way out , end up on the surface BUT something had changed in him left us wondering about that .
well you played as a big daddy who search for little sister to get the ADMA ( like mana used to cast special spells ) .
you have to fight another big daddy like you to have his little sister to be yours .
after that you have to search for a body of dead splice to let the little one harvest ADMA for you the spliceres of the area will try to steal the ADMA during the harvesting .
after you get ADMA from little sister (either by harvest her or rescuer her )the big sister come to the picture now, she wants to kill .
See the events above it will repeat and repeat each stage and level .
With people talking to you by radio or learn about them by playing records, it have multi ending, I didn't bother myself about it cause I played it for my poor money I paid for it:

2. Graphic = 9.5
3. Weapons = good selection 8.5
4. Sound = 8
5. Storyline=6.5
6. Play it again = absolutely NO
Then my rating is = 8
