The Shaky Ground has now been reviewed for the CGS website, it's a lenghty article that dives deep into several aspects of the episode: the individual maps, the soundtrack, gameplay, design and the experience of the episode as a whole. Here's a small quote:
"Conclusion: I am positive this is just the best thing I have played for Duke during my 20+ year adventure with this game. Merlijn just managed to make a consistent, extremely entertaining episode, with immersive story, strong atmosphere, masterful design and epic scale, balancing out the pace and tone and topping it off with complimenting music."
It got a whopping 100 out 100, which of course makes me really happy! You can read the whole review here: Scent-88.com
