I'll use this thread to update you on developments for the planned Trail of Cthulhu, Eternal Lies to be written by Will Hindmarch. The initial release info says:
A decade ago, a band of occult investigators battled against the summoning of an ancient and monstrous evil.
Now, you must piece together what went wrong. Investigate ancient crypts, abandoned estates, and festering slums. Explore choked jungles and the crushed psyches of your predecessors. Follow in their footprints and make new ones of your own. This time, there won't be another chance.
The world is yours to save - or lose
