Hitbox issues are commonplace in hero shooters, and Marvel Rivals is no exception to this rule despite how well it has been performing since its launch. Plenty of players have reported issues with the overly generous hitboxes. While these help most actually land some shots, it does come across as frustrating when a Hawkeye kills players without aiming near them. Overwatch and its sequel continue to have hitbox issues, and hero shooters aren’t the only ones who suffer from exaggerated hitboxes. Even PvE titles aren’t immune to exaggerated hitboxes.
