Poster Duty is a minigame that can be played by Sora and Roxas in Twilight Town in Kingdom Hearts II although only the former receives munny for it. In Poster Duty, Sora/Roxas has to go around the Tram Common area of Twilight Town putting up posters in designated areas. The goal is to put up 20 posters in the less time possible. The less time Roxas takes to put up the posters, the more munny he will receive.
- The posters advertise a Struggle tournament, a competitive game of combat that the inhabitants of Twilight Town often play.
