In Mystery Duel, each team is made of only one player. There is no objective in Mystery Duel; the only goal is to kill the enemy player. Each round, both players will be randomly assigned a hero (excluding Lúcio and Mercy). The hero will be displayed at the beginning of the round in the victory pose either player has equipped. If one player kills the other, that player receives a point and the next round begins. The game will continue until one player earns 5 points, winning the game.
