If it were to go down, Castle's Nathan Fillion and his wise, but no so serious words would come handy.

Minecraft Xbox 360 Edition is pouring on the fan service with this week's release of Skin Pack 4—providing delightfully low-res interpretations of Claptrap from Borderlands, Klei's Mark of the Ninja and The Behemoth's Castle Crashers, plus a whole lot more.

Brandon Keener, also known as the voice of Garrus Vakarian, made an appearance on ABC's Castle this week. You can even hear tinges of the rogueish turian when Keener's voice gets real low. And he didn't even have to calibrate anything.
