The Neverhood came out over 16 years ago. While it did receive a sequel for the PS1 (Skullmonkeys) that was also claymation, it was a platformer rather than an adventure game. A true sequel for The Neverhood (or any sort of game to add to the series) still isn't in sight, but we may be getting a new adventure game from Doug TenNapel.
This exciting bit of info comes from the official Facebook page for The Neverhood, where TenNapel tells fans that he's working on a "full sized, PC and Mac point and click adventure game in clay and puppet animation." He'll be partnering with his Earthworm Jim and The Neverhood buddies, Mike Dietz and Ed Schofield. Terry Taylor will also be creating the music for the game. New characters will be made, but will be in TenNapel's usual art style.
Lastly, TenNapel requests something from you. Ideas! What do you want to see in this new point-and-click claymation adventure game? Post on the Facebook page and your comments will definitely be read and considered.
