Lost Soul Aside, UltiZero Games' action RPG, a sourced analysis
Lost Soul Aside is an action game with RPG elements developed by UltiZero Games and published by Sony Interactive Entertainment on PS5 and PC. A summary of official information and two reviews of the PS5 version; this is not a hands-on TricknFix review.
Game trailer
Kaser and his dragon weapon
Released on 29 August 2025 on PS5 according to the French PlayStation Store and on 28 August 2025 on PC according to Steam, Lost Soul Aside follows Kaser and Arena, a dragon creature that transforms into weapons. It focuses on fast combo-based combat, perfect dodges and big bosses. It began as a single developer's project before being supported by Sony's China Hero Project.
What the press says
On PS5, Push Square (6/10) praises an intricate combat system, some great boss fights, lots of room for expression, a cool weapon selection and a rich, varied soundtrack, but criticises a generic story, very dull characters, attacks that lack weight, later foes that are a slog, performance hiccups and a companion who never shuts up. PlayStation Universe (5/10) finds the combat enjoyable, the bosses epic and the soundtrack often excellent, but calls the game outdated, uninspired and technically messy.
Editions and prices
Checked on 12 November 2026: on the PlayStation Store the game is on sale at €29.39 instead of €69.99 until 21 November 2026 at 00:59 (Paris time), and the Digital Deluxe Edition costs €79.99. On Steam the game costs €69.99 with no sale. The PlayStation Plus trial is not counted here.
Who is it for?
Fans of combo-driven action games who care more about combat than story. Players expecting a polished story or flawless technical performance may be disappointed.
