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.
The start to a very good series of games.
The best selling point for the whole Bishock series has to be the atmosphere. Set in a great era, Rapture clearly captures one man's post war vision for an elite society.
The gameplay is simple to get to grips with, and the options of different plasmid/weapon combos make it suitable for all gamers to find their preferred combo.
