After a week being closed, the changes to Nemesis Sub-Terra are both considerable and widespread. Here's a rundown which I noticed, from my two rides at the weekend!Briefing Area
No major changes, although the video is now louder in volume. Obviously, on opening weekend there wasn't even a video at this point.Descent Lift
Spoken audio is the same, to instruct guests on boarding procedure. Accompanying this, there is now a droning sound which lowers in pitch as the lift descends into the cave. The vibrations are also more effective now, and there is a better sensation of going down. Generally louder. The cavern which guests walk through before entry into the observation chamber is the same, although the main chamber doors now do not open until several seconds after exits from the descent lift - so guests usually see them opening towards them.Observation Chamber
New lighting on the egg, and a louder "heartbeat" noise accompanies this. The sequence/programming has changed a lot. The introduction at the start is now longer, before anything happens - then there are vibrations in the seat caused by heavy bass. Lights dim, various loud noises, egg hatches as before but much heavier water spray hits guests. Various "malfunction" messages play out, and lights dim again. Gondola's drop at different times. Nest of eggs very clear with new lighting flashing. Very loud noises play, speakers in seats to make it seem like the alien is moving around the room (this in darkness). Air bursts on back of neck. Lots of back poking and leg ticklers. Upon rising back up, countdown "30 SECONDS" begins, to get out of the main chamber. Very heavy strobing at this stage. Much more urgency. Guests leave seats and head towards Escape lifts - the room between main chamber and lifts is now full of smoke, air jets from above and heavy strobing. Lots of noise!Ascent Lifts
More smoke through new panel. Lighting changed, more banging and more noise. Generally more "stress" going on here. You see a panel break at the top of the lift. Upon lift doors opening, a Phalanx Operative in gas mask from the decontamination unit bursts in with a flashlight, scaring all guests. Very effective here.Decontamination Area
Entirely new. Lack of narrative here at the moment, although we were informed that this was being looked at. Guests go through decontamination in darkness. Phalanx operatives in gas masks, lots of flashing lights, strobes and bangs. Impression that a room has caved in as guests go under a fabric cloth. Lights have failed. Lots of mesh fencing. Very loud bangs just before exit.
And that... is the new Sub Terra. A massive improvement - well done Alton Towers. Now, just for a little improvement on the narrative side of things in the decontamination area and things will be well sorted!
