An actor has posted the above image to instagram as well as the following:
Had a blast doing motion capture work as the lead character in a new video game series! (= #actor #motioncapture #artist #videogames #ps4 #xbox #art #work #comingsoon #WatchDogs2
To be honest I can see this being real. Ubisoft has said that Watchdogs 2 would launch before the end of next year, meaning an official announcement could be soon. And every so often actors aren't aware of how much digging video game fans are capable of. Mistakes like this happen every so often. Having said that, take this with a huge grain of salt until Ubisoft makes an official announcement.
