Quoted from anathematize:The MUMMY lock location changing to the left ramp on the Premium/LE is a HUGE and game altering change on Iron Maiden. Makes MUMMY multiball and collecting Tomb Treasures much harder if you aren't dialed in on your ramp shots.
Also the Premium/LE has an entire multiball mode (can i play with madness) that the pro version of the game doesn't. Another huge change.
Starting mummy mb is probably harder; but collecting tomb awards is easier. The right loop isn’t used all that much in the code and is one of the harder/riskier shots in the game making it tougher on the pro. From my experience, prem = longer game times do to easier difficulty and more stop n go while the pro is faster. But all in all, it’s not by much.
I’d like to hear more on DP. I think the premium is the way to go there solely for the flow of the left loop diverted returning to the flipper rather than pops.
