Hacking in Bioshock 2. Plenty of folks would go BAAW at me after saying that but really - it's good, minigame that is - and seriously, who of you actually played the damn game?
It's neddle sliding left and right, you can stop it with a button, the goal is to stop it at the right moment.
It's over quick - you have time limit. It doesn't have simple binary execution, no just win/lost&reload but win+/win/no-consequence/critical-failure with gives player space to perform better. It have difficulty progression, at the end of the game I was not capable of executing it without critical failure(there are upgrades(?) making it easier, I didn't use them). It require skillz. And it has place in gamespace and is directly connected with standard gameplay - when you are performing hacking monsters still attack you etc. It makes hacking harder during fight. Actually I was not able to multitask good enough to hack and fight at the same time, could only hack away from monsters or very fuckin' quick. Hmm, there is bayout? I didn't remember that.
There are also tools with darts allowing hacking at the distance and auto-hack. It's nice.
Of course it have its share of problems but not particularly big. When you hack shop terminal and manage to win+ you get bonus item. Sucks because it encourages hacking everything, not just things you very much need. it would be better with just bigger discount - turrets and security bots have something like that.
btw: sry for xbawks screenie, no KKK for me
