BioShock is a shooter unlike any you've ever played, loaded with weapons and tactics never seen. You'll have a complete arsenal at your disposal from simple revolvers to grenade launchers and chemical throwers, but you'll also be forced to genetically modify your DNA to create an even more deadly weapon: you. Injectable plasmids give you super human powers: blast electrical currents into water to electrocute multiple enemies, or freeze them solid and obliterate them with the swing of a wrench.
This game surprised me. It turned out much better than I thought it would be from first looks. It was just bursting with color and originality around every corner. The art and story were outstanding. The weapons and hacking systems were elaborate and a bit unnecessary for the simple combat of a single player RPG; however, even if I didn't use 95% of it, it was fun to collect those powers. On the character of Andrew Ryan, he was interesting. On the second play through I think I understood him better.
Now for the negative points: I didn't feel comfortable with the controls and movement in the Unreal Engine but that's not very important and it didn't affect my enjoyment. I found it difficult to find places in those maze-like halls. When listening to recorded messages they would often be interrupted by another character or shut out by other loud noises. I probably didn't hear the whole story which made some points confusing. The splicers got really old really fast, especially annoying after the place where Jack discovers who Atlas really is. Hoards of them came screaming out of nowhere and surrounded me while I fire at random past the smoke and flames they were throwing at me. I only died a few times in total but it *felt* really hard. Overall the combat was not so good but just okay. (Maybe some of that is also part of my difficulty with navigation.) The little sister guiding you to the end said "Don't be a slowpoke, Mr. Bubbles" about every ten seconds even though I was way ahead of her while she lagged behind going a snail's pace unknowingly surrounded by psychos trying to kill her. This provided some unwanted tension right before the final battle. The "good" ending that I got felt a little too abrupt.
Overall this is a great game that excelled in many areas, although with some flaws. All that matters is that it was immersive and fun, in fact, the best fun I had in a while, and that earns it a 10.
