- Resident Evil Survival Unit JOYCITY studio monitored testers’ brainwaves to make game ‘objectively scary’
- Sales manager Jun Seung Park said the team “achieved significant results that helped us adjust the fear and immersion levels.”
- The team also referenced the main series to “capture the same unique feel on mobile devices.”
South Korean studio JOYCITY, the developers behind Resident Evil Survival Unitapparently monitored the brainwaves of game testers to make sure the game was scary enough.
This is according to JOYCITY business manager Jun Seung Park, who told This Is Game (automatically translated by Automaton), that the developers wanted to make sure the mobile game was “objectively scary” for players.
“We conducted a group test based on biological signals, monitoring players’ brain waves, eye movements and pulse to objectively measure their tension and immersion levels,” Seung Park said. “Even if we received positive responses through surveys, looking at actual biosignals might lead to a different conclusion. Using this data, we obtained significant results that helped us adjust fear levels and immersion.”
A documentary-style video on JOYCITY’s official YouTube channel shows a group of testers wearing said brainwave measuring devices strapped to their heads. So it’s clear that the studio has done everything possible to try and increase the fear factor.
Seung Park also discussed the reference to the original resident Evil games and said the team tried to “capture the same unique feel on mobile devices”, even going so far as to mimic the series’ sound design, particularly the sound of footsteps in a scene without background music.
“Capcom’s 30 years of accumulated know-how has proven invaluable,” they said.
Producer Dongkyun Kye added, “At first, I wondered if this kind of approach would be effective, but seeing how surprised and tense the players were in these moments made me feel relieved.”
It’s also worth mentioning that since this is a machine translation, some additional context and nuance may be missing from Jun Seung Park and Dongkyun Kye’s comments.
Resident Evil Survival Unit launched discreetly on mobile last November and went unnoticed, even by the biggest resident Evil fans. Reception was lukewarm to say the least, with some players praising its exploration but criticizing the game’s lack of horror, limited-time purchases, and overpriced microtransactions.
resident Evil fans who don’t like mobile games can look forward to the next main installment, Resident Evil Requiemwhich will launch on February 27, 2026 on PlayStation 5, Xbox Series X, Xbox Series S, Nintendo Switch 2 and PC.
