Revenge of the Mummy Ride, Sentosa Island, Singapore Singapore

The coaster part of Revenge of the Mummy does not have any inversions, does not do to any uncomfortable speeds, and reaches a relatively tame max speed of 45 mph. RWS even considers it a "family" attraction and it's less intense than Battle Star Galactica Coasters. But it does include high-speed launches, delivers some startling drops and out-of-your-seat airtime, and feels a lot more out of control because it is in the dark. Be prepared for a more aggressive ride. There will be moments where you feel that you will drop out of your seats, and some "uncontrollable" turns in the dark. There are also steep drops, but still still can be managed. The Linear Induction launch is an aggressive part of the ride, and it launches you straight into a fog filled room, so for those sensitive to fog, you may need to consider it twice. There is a backwards section to the ride too, but it is short, and more fun than intense.

On the "psychological" side of the thrill equation, I think just about everybody, save highly impressionable young children, will find the mummy motif more engrossing than gross-out. The sound effects will be loud, and there will be strobe lights and pyrotechnic effects (real flame).
If you're on the line, I'd advise you to suck it up, hold on tightly to the rider next to you and give it a try. Revenge of the Mummy is among the very attractions in USS, and you should try it at least once. Even if you find the ride a bit too unsettling, you'll be able to take comfort in its short duration; the whole experience lasts about three minutes, with the coaster portion taking less than half that time.
