Mafia: Definitive Edition - "Alien Infiltration" (Herbert Baskerville Side Mission)
Accessible in the "Free Ride" mode of the game, with a note from Herbert in Salieri's bar after completing his first challenge, "The Crazy Horse." Unlocks the alien costume/mask. This is one of the hardest side missions in the game. HINT: The UFO flies to the exact same locations every time you play the mission; they are marked in the video.
