After Jack clumsily sprinted across rooms to hack turrets whilst being shot in the face in BioShock, the protagonist of the sequel takes a much more elegant approach. Hacking in BioShock 2 is less of a puzzle and more of a quick test of time and precision. Stopping a dial in the right spot as it moves back and forth isn't anything to intuitive, but compared to the "hacking" present in its predecessor, it's the holy grail of game mechanics. Whereas most hacking systems pause the game to give the player a chance to think, the challenge here occurs in real-time, forcing players to be on their toes. Whilst other hackers might grab a cup of coffee and relax as they think over their next move, Johnny Topside has to hack on-the-go as he protects genetically-engineered little girls, shoots disfigured cultists in the face with a machine gun, and loots money out of trash cans. That level of multi-tasking has to be admired.
