The beta launches today, which is a fully functioning version of the game minus a few extra scenarios and the river rapids. They will launch will the full release next week. For £3 extra it made sense to buy the game and play it from today. The game is not in a buggy state at all either, you can tell from the alphas, this is mirrored in the fact they launch the full release next week.
Their pre beta live stream the other day was probably one of the best live streams to date, this game is jam packed with stuff. A few of the things they confirmed and showed were the following (and they all look stunning!)
-Wooden coasters
-Hybrid coasters
-Log flumes
-River rapids
-Dark rides (including triggered lights, animatronics, scenery, music)
-Toggable catwalks for all coasters
The support systems on the wooden and RMC look absoloutly amazing, beams, spacers and walkways all in the right place, all generated automatically and all look true to life. They said they had spent close to 2 years working on the wooden coasters and RMC coasters and support system alone and it shows!
I am like a kid at Christmas, I can't wait to get home from work and download this on Steam and play later today. They really have delivered on a next generation theme park simulation game.
