Mike Donatelli, late of Carbine Studios, has posted a sneaky teaser on one of his social media channels about a new project called RiME. There is no other information available other than the fact that more will become known in 2017. Greybox, Tequila Works and SixFoot are listed on the page as being involved with RiME.
We'll keep you posted!
