Marvel Rivals open beta
Definition
A widely anticipated promotional trial phase for the hero-shooter video game 'Marvel Rivals', wherein players test the game's mechanics, character balancing, and server stability prior to the official commercial launch.
A period of chaotic digital carnage where players realize their favorite superhero's ultimate ability is just as unbalanced as a mid-tier comic book reboot.
