It looks like that manga jacket from earlier was correct in spoiling the title that Koei Tecmo and Omega Force has been teasing over the past week as the company has officially announced that they are working on an Attack on Titan game for the PlayStation 4, PlayStation 3, and PS Vita.
Few details about the game are known at the moment, as it is simply called Attack on Titan (Working Title) for now, but it will be an action game based off of the hit manga and anime series and will be released in North America, Europe, and Japan sometime in 2016. You can check out the teaser trailer below.
