You have to hand it to Treyarch, they always seem to deliver those little tidbits in their games that pleases many fans. A while back someone found the Thor easter egg within the game. Now another gamer has found something even more epic, a Batman easter egg!
If you’re like me and have a big “WTF” face right now, I totally understand. I really don’t get the basis behind it either, other than just doing it. If you check out the video, ChaosXSilencer on YouTube details everything out for us.
It all takes place on the “Hijacked” multiplayer map in Call of Duty: Black Ops II. Within this map you even find little clues, right down to Christian Bale’s favorite childhood books. Follow all the instructions carefully (and there are MANY), and you too can have the Dark Knight appear out of the ocean.
...BTW if you haven't realized that this is more than likely very fake, then I don't know what to tell ya.
