Why So Serious

Why So Serious is an achievement in Halo: The Master Chief Collection. This achievement is obtained by viewing the smiling face easter egg on the Halo 2 multiplayer map Coagulation.

Trivia[]

The name is most likely a reference to the line spoken by Heath Ledger's Joker in 2008's The Dark Knight. In the film, the Joker explains that he recieved his facial scarring from his drunk father, who attacked him with a knife while repeatedly asking "Why so serious?"^[1]
