Like a number of other video games of the same genre, Arms also allows players to select between four different costume colors for each character to play in. When selecting a character for any game mode, all a player must do is hold in on the left analogue stick, and while they are pressing it in, angle it in one of four different directions (Up, Down, Left, Right) before pressing the button to select a fighter. If done properly, a player's fighter will be selected from one of four separate costume skins.
