Currently, there is a new drop sequence program known as Tower4. The drop sequence isn't actually randomly generated. There are four pre-programmed drop profiles (three new ones, and a slightly modified version of the existing "Twice the Fright" profile), and each time a vehicle enters the drop shaft, the ride computer randomly selects one of the four profiles, so it's not like it's actually making up a new ride each time, there are just many to choose from, as opposed to the same one each
time. The new profiles are enhanced by some new audio, smells, and a few other animatronics and visual effects.
