Rode Sub-Terra for the first time ever today and wow, I am absolutely blown away. I had really high expectations going in and these were certainly met. Thought I might have had issues fitting onto the ride, however no issues this time! Staff were great too and knew exactly where to seat everybody to make sure everybody could ride.
I assume all effects that are supposed to be working were working (smoke from the egg, leg whippers, water, back pokers, smoke in the second lift etc). I couldn't fault the ride experience itself at all! The only part I would say was a bit lacklustre was the ending. It just seemed like it was missing something. Maybe some more smoke, strobe effects and air cannons? (I believe it may have been more like this when it was open the first time around?).
Other than that, NST has without a doubt become my favourite attraction at Towers, and overtakes The Curse as my favourite dark ride. Very impressed.
