The Chainsaw Controller was a collector's item created by by Nuby Tech for the Nintendo GameCube survival horror game Resident Evil 4. Based on extensive playtests, Nuby Tech's claims that its chainsaw controller actually improves the Resident Evil 4 experiences are false. The device features all of the standard sticks and buttons of a regular GameCube controller, but lacks an intuitive configuration. The two analog sticks, D-PAD, A, B, Y, X and START buttons are mapped to the face of the chainsaw controller. Meanwhile, the L and R buttons are assigned cumbersomely to each handle and the Z button is hidden away underneath the peripheral's face groove.
Trivia[]
There was also a version of this controller for the PlayStation 2.
Pulling the ripcord of the chainsaw would register a Start button press as well as making a chainsaw noise.
