Some heroes excel at taking objectives solo in Marvel Rivals. This mostly comes from avoiding the enemy entirely, such as using stealth, moving incredibly fast, or full on warping to the goal. To achieve this, the opposition has to already be careless and leave the objective open for the taking. This mostly occurs on Convergence and Domination maps where the enemy might get agitated or bored waiting for you to advance. However, it is sometimes also possible to steal the Convoy from under their noses.
