Russell is a mask unlockable in Hotline Miami. The mask is of a bull, and when worn by Jacket, it gives the game a black and white filter, with the exception of the UI and blood. This mask is exclusive to the PS3, PS4 and Vita versions of the game.
The Russell mask can be found at the end of Prelude (Metro) directly to the left of where you throw the briefcase into the dumpster.
- The description for this mask reads "Raging Bull," suggesting that the mask is an homage to Martin Scorsese's black and white boxing film of the same name.
- It could also be a reference to the misconception that bulls are angered by the color red (bulls are actually red-green color-blind).
