If you're a hardcore gamer then you may be ready for the Limited Edition Saints Row 4.
It's called Saint's Row IV Super Dangerous Wub Wub Edition
Along with the game you get a replica Dubstep Gun that features plenty of wobbles for some Bass action during gameplay. If that's not enough for you then check out the Bass Drop BIG Red Button, called a Doomsday Button, with its own special case. Wob Wob Wob!
To round things up there's a limited edition model of Johnny Gat.
