The Rasmus Mask is a mask obtainable in Hotline Miami. The mask resembles an owl, and when worn by Jacket, the puzzle pieces and hidden masks bounce slightly and become easier to spot.

In Hotline Miami 2's Level Editor, the mask gives no perks as there are no secrets. Rasmus is also a nightmare entity Jacket meets occasionally.


This mask may be obtained by achieving a high score in Prelude (Metro).


  • This mask is a reference to Dennis Wedin's (one of the game's creators) younger brother Rasmus, whose favorite animal is the owl.
  • 1987 giallo film Stage Fright features a serial killer in an owl mask turning a play rehearsal into a bloodbath.
