Mortal Kombat: Onslaught

Mortal Kombat: Onslaught is an action-adventure beat 'em up role-playing video game, developed by NetherRealm Studios, released on October 17, 2023. Part of the Mortal Kombat franchise, it is the fourth installment to not be a fighting game and combines the combat gameplay with a full cinematic storyline, reminiscent of free-to-play mobile multiplayer online battle arena games. It began location testing on October 31, 2022.

Developer Ed Boon stated about the development of the game, "We are pushing the boundaries of Mortal Kombat to allow players to experience the franchise in new ways, while still staying true to its core visceral nature... With Mortal Kombat: Onslaught, we reimagined Mortal Kombat into a strategic team-based collection [role-playing game] with fast-paced, group melee combat that both new and existing fans can enjoy."

In July 2024, following the reported closure of NetherRealm's mobile division, the company announced that Onslaught will shut down in October 2024.
