Sierra's latest is a puzzle platformer called Shiftlings
Sierra seems to be warming up to its role as Activision's indie label, announcing the upcoming release of Shiftlings.
Developed by Rock Pocket Games, Shiftlings is coming to PC, PS4 and Xbox One in northern spring this year.
It features two "adorably dim-witted alien space janitors" joined by an air hose. By shifting size and weight between the two characters, players can solve puzzles to avoid traps and resolve problems.
You can play alone or in online co-op across 50 levels, set on five different planets each dotted with collectibles.
