Built on Unreal Engine 4, the single-player souls-like slasher allows the player to assume control over Kaser, aided by his companion Arena, a character capable of transforming into weapons and other elements useful in battles and throughout the journey, as they embark on a quest to rescue Kaser’s sister, Louisa, and save humanity from the Voidrax, mysterious invaders from across dimensions.

Lost Soul Aside’s aesthetic was heavily inspired by Final Fantasy XV, while the title’s hack-and-slash combat takes inspiration from Bayonetta, Ninja Gaiden and Devil May Cry.
