Actually, the projection of the Batman symbol on buildings is the idea of DC Comics. On its website, it published a list of cities in which the flash mob will take place. One could assume that WB Games Montreal just joined the action, but there are two nuances. The first is the Twitter account of the creator of Batman: Arkham Origins has not been updated since 2015 (it was then that the last franchise game from the studio came out). The second. in the video you can notice strange inserts in the form of runic characters.
Therefore, it is possible that the studio teaser the next game about Batman. Perhaps soon we will see the announcement.
