– Garbled AI-generated text in *Stellar Blade: Blood Rain* key art and trailer suggests genAI tool use has drawn criticism.
– Analyst Daniel Camilo warns that garbled Chinese characters could hurt sales in China, which accounted for over 60% of the original game’s PC audience.
– Shift Up CEO Kim Hyung-tae supports genAI as a productivity tool for smaller Korean studios, but its final role in the sequel remains unclear.
– Beyond AI concerns, the sequel faces backlash over its youthful protagonist, Evie, adding further controversy.
Generative AI has become an increasingly common resource in game development. Regardless, that hasn’t stopped the scrutiny of studios that rely on the technology. Most recently, there have been concerns about the Stellar Blade: Blood Rain trailer that premiered at Summer Game Fest 2026.
Suspicious Details in the Trailer and Key Art
The video has several telltale signs that genAI tools influenced its production. Even in the key art used by Shift Up to promote the Stellar Blade sequel, windows on buildings resemble AI slop. Daniel Camilo, on social media, focused on Chinese characters that don’t translate to anything coherent.
Persistent Flaw of Garbled Text
While machine learning now produces more convincing images and videos, garbled text remains an issue. It’s possible that the suspicious artwork is a placeholder ahead of the Stellar Blade: Blood Rain release date. Nevertheless, Camilo thinks that it could hurt sales from one of the largest customer bases.
Formerly a PS5 exclusive, Stellar Blade debuted on Steam in June 2025. The PC port’s success surprised many analysts, with one Asian country significantly boosting sales. Gamalytic revealed that over 60% of the audience of the stylish hack-and-slash RPG hailed from China.
Multi-Platform Launch and Familiar Setting
The follow-up will likely launch on multiple platforms, with many of the same buyers anxious for the sequel. Its setting could also attract players who find the scenery familiar. Some fans believe that the city of Chongqing inspired the Cyberpunk-themed trailer.
Shift Up CEO’s View on Generative AI
How much of a role generative AI will have in the final build is unclear. However, Shift Up CEO Kim Hyung-tae is a strong supporter of the technology. He previously explained that smaller Korean companies need the tools to compete with larger western and Chinese studios. Still, the executive says it should increase productivity rather than create assets.
Even if the Chinese characters are overlooked, Blood Rain will not escape controversy. Other critics argue that its youthful protagonist, Evie, is a questionable choice for the sequel.
