Key UE5 features fuel supernatural Soulslike Valor Mortis

Based in Krakow, Poland, developer One More Level has spent over a decade crafting a wide variety of daring and unique gaming experiences for PC and console. From 2014’s strategy-infused arcade side-scroller Deadlings to 2019’s graphic, over-the-top shoot-'em-up God’s Trigger, One More Level certainly doesn’t suffer from a lack of originality. 

Most recently, the team of roughly 60 people used Unreal Engine 4 to craft 2020’s Ghostrunner and 2023’s Ghostrunner 2, which offer a unique blend of one-hit-one-kill mechanics, parkour, and cyberpunk aesthetics designed to fulfill every fan’s fast-paced fantasy of being an elite cyber-ninja.
Now, the team at One More Level are digging deep into Unreal Engine 5’s most modern tools while taking players back in time to 19th-century Europe in Valor Mortis—an all-new first-person action Soulslike where players rise from death as a former soldier of Napoleon’s army to wield supernatural powers, battle horrifying monsters, and unravel a conspiracy that threatens all of humanity.

How’s that for originality?

So, what type of research went into crafting the locations, weapons, and even outfits based on an alternate 19th-century Europe, and how did UE5 help bring these elements to life? Also, how did specific UE5 features such as Nanite, Lumen, and Niagara help craft the game’s Metroidvania-inspired levels and dynamic visual effects? We caught up with the studio’s Technical Director, Krzysztof Dalton Pachulski, to find out.
