Going through the list of the trophies and medals in Uncharted 2, one spots a yak-petting exercise called "Beast Mode." Jacob Minkoff, of the studio Naughty Dog, explained its origin with a laugh.
"There was a tester we had who came in and was constantly describing Drake as going into 'beast mode,'" said Minkoff, a designer on Uncharted 2. "Like, 'Man, I went into beast mode and merced those fools!' And I said, 'We need a beast mode medal.' It had to happen."
