I find AC/DC premium is just punishing/frustrating. Any type of missed shot is deadly but worse is when you hit the shot and it drains as reward. You have to be good and lucky to get a good score... use the canon, hit target then...drain...argh! Shoot the ramp, almost makes it up, rolls back then...drain SDTM! Shoot the bell, ball returns then...drain SDTM! Hit TNT target then... drain straight into left outlane...
I own STTNG and TS, it's tougher than both these.
The best way to keep your game times up is to go for multiball as often as possible..
