Now here's the thing about getting through this game. When you play it on a higher level, it's easier, not harder. I got right through to the end of the Jailbreak section on Hardened Detective level -- in a few hours -- because I knew what to do.
Unfortnately my game computer seems to have bugged out on me, so I won't be continuing for a while. But anyway the first run-through the game is the tough one. After that Jack's in command -- er, well, sort of -- right until the end.
No fancy-pantsy Elven dagger-twirlers. Just tough guys.
