It will be interesting to see how this changes the alien/monster which acts as the station. The track is literally coming out of the tentacles at points as part of the themeing. With the track now being black, will the monster go from white/grey/pink/red to black/grey/pink/red? Will we be seeing the alien become a bigger badder boss of its older self? I hope so. Maybe radiation has caused it to mutate! >.< Still hoping for the next nemmy comic.
Edit: Also agreed about the campaign. While i'm still not 100% on the veins (although i like them more with the track in place), the campaign so far has been brilliant. The original Oblivion campaign is still my favourite. But the actors, the trucks, the phalanx, the video updates, this is a very theatrical campaign and i'm really enjoying following it. I hope Towers keep this up for the indoor coaster/attraction too.
