I went on Tomb Blaster back at the beginning of August and most of the targets weren't turned on and half of the effects were not working. I was so disappointed after hearing that the ride received a revamp.
A large number of the targets have been turned off on purpose as part of the changes to the ride's narrative... It's all in an effort to make the ride darker. All of the effects were working when I went on it on August 4th. You must've had an off day. Even the boulder was working, which is astonishing considering how temperamental that thing is.
