Mortal Kombat: Onslaught is a role-playing game that includes action and adventure, a collection of heroes, and beat 'em up gameplay elements. It serves as a spin-off from the main Mortal Kombat series and allows the player to build their own team of Mortal Kombat characters and engage in RPG battles.

However, despite being part of the Mortal Kombat franchise, the core gameplay mechanics and overall style more closely resemble games like AFK Arena and RAID: Shadow Legends.

Story-driven adventure

Mortal Kombat: Onslaught is a mobile RPG set within the MK universe. It represents a significant departure from the fighting game style the series is known for and is instead a story-driven role-playing game with a focus on group combat and hero collection mechanics.

The story itself is not part of the Mortal Kombat canon. Instead, it is set in an alternate timeline between the stories that play out over the course of Mortal Kombat X and Mortal Kombat 11.

A familiar cast of characters

The game is a mobile-exclusive release available for Android and iOS devices. Its departure from the format of the main Mortal Kombat series may not completely satisfy long-time fans of the franchise. Still, all the familiar MK characters, including Scorpion, Sub Zero, Sonya Blade, and Johnny Cage, are all present.

Loot and leveling up both play a key role in the game. Leveling up is achieved by amassing souls, while loot is collected as players progress. Moreover, players continue to amass loot even while the app is closed. This, combined with auto battler mechanics, is where comparisons with AFK Arena are the most apparent.

Engaging RPG spin-off

Overall, Mortal Kombat: Onslaught serves as an entertaining and engaging RPG spin-off, with the hero collection mechanics and abundance of loot providing plenty of incentive for players to return to the game regularly.
