In Grasshopper Manufacture's Shadows of the Damned, hero Garcia Hotspur has a demonic pal named Johnson that can transform into various weapons, tools, and even vehicles. Why? So they could release an 'Enlarge your Johnson' video.
Part of me wants to believe this entire game was developed and funded specifically to make this video. It seems unlikely that Grasshopper and EA would work together on the world's most expensive dick joke, but then this is a game co-created by Goichi Suda of No More Heroes fame, so I wouldn't write off the idea completely.
Shadows of the Damned visits the PlayStation 3 and Xbox 360 on June 21. You'll have to keep your hands off your Johnson until then.
