During last night's EA press conference (that was totally a part of E3 even though it wasn't officially a part of E3) the publisher announced it was pouring money into a small developer's project, much like it had with Unravel the year before. The game is called Fe and sees you playing a young cub exploring a dark forest.
It looks quite lovely but you don't need to take the trailer for read: there's already a secret demo of the game out in the world that was released back in October.
Before Fe, developer Zoink! made a game called Zombie Vikings. Hidden in the undead Viking hack and slash was a single level from Fe.
Here's a playthrough of the level:
