Does Watch Dogs feature Bruce Wayne?
Solution 1:
There is a civilian profile for "Bruce, Wayne", but this is just an Easter egg. Neither the real Bruce Wayne nor Batman are actually in the game. It is just the game playing a joke on you, making it a hoax.
Solution 2:
The bat is a lie. The only thing I can find about this is a video on YouTube, which is fake. There's a Wayne Bruce who's into BDSM, but there's no Bruce Wayne millionaire vigilante.
