Given common fan discussions, I’ll assume refers to the show’s major technical/narrative components: Action, Mystery, Romance — OR you might have meant “S3 and MR” (Melanie Return) .

It seems you're asking for a of Snowpiercer Season 3 — specifically regarding its AMR (apparently a typo or shorthand; likely you mean “AM” as in Archives Management , “MR” as in Mystery/Romance , or perhaps you intended “S3 EMR” — but most probable: you want the entire feature set / story arc for Season 3 with a focus on the “Armor” or “Aram” ? Or maybe “AMR” = A New Resistance ?).
