Oh my, how'd I miss this? Only after reading a short article on procedural worlds in the new EDGE magazine, did I manage to find this thread tucked away on this here forum. Phrases like 'Tweed-loving British science fiction', 'British indie S.T.A.L.K.E.R.', 'Lo-fi indie open-world shooter' and 'Foliage-based stealth system' was supposed to have piqued my interest must sooner than today. Nonetheless, I'll be keeping both eyes on this one.
The game's British Countryside Generator engine sounds especially interesting.
