Prime Video has released a new trailer for Fallout Season 2 ahead of its debut in December, and it shows off two of the new cast members for the sophomore season: Macaulay Culkin and Kumail Nanjiani. We don't know much about the characters they are playing, but we see Nanjiani's character getting called in for a battle and Culkin's character murdering someone. The trailer also spotlights one of the new settings for Season 2, New Vegas, and overall includes numerous spoilers.
