A very strange teaser trailer was released recently for an upcoming video game from the makers of the Mass Effect and Dragon Age franchises, BioWare.

No one knows what the game is yet, or even what it’s actually called. All we have, at least for the moment, is something stating “You’ve Been Chosen” from a YouTube account of the same name, and this teaser trailer labeled “Nightmare“. Whether the game’s final title will actually be You’ve Been Chosen or Nightmare or if it will later be revealed to be something else, familiar or brand new, is a question that remains unanswered.

You can watch the teaser trailer below.
