WWE Undefeated (2021) was a mobile real-time strategy fighting game that blended WWE action with fast-paced competitive mechanics. Players used a mix of moves and counters in card-driven combat, with each superstar having unique abilities. Matches were short and tactical, designed for online play.

The stylized graphics and emphasis on head-to-head battles set it apart from traditional WWE games. Though its lifespan was limited, it provided a unique experiment in blending fighting game design with WWE branding.
