Duel or 1v1 mode is unlocked at level 10 and consists of only two players. It can be played on a variety of maps. In this game mode, two players compete against each other by earning 5 kills before the other player reaches the same goal. Whoever reaches the goal of 5 kills first, wins. If neither player reaches this goal, the player with the most kills wins. This mode can be accessed through the Daily Event through chance.
One of the most common methods to win is using a sniper (Black Mamba or Target Rifle) and killing the enemy before they get a chance to kill you.
