South Korean studio JOYCITY, the developers behind Resident Evil Survival Unitapparently monitored the brain waves of the game testers to make sure the game was scary enough.
That’s according to JOYCITY business leader Jun Seung Park, who told This Is Game (automatically translated by Automaton) that the developers wanted to make sure the mobile game was “objectively terrifying” for players.
“We conducted a focus group test based on biological signals, monitoring the 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 could lead to a different conclusion. Through 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 went all out to try and up the scare factor.
Seung Park also talked about referencing the original. resident Evil games and said that the team attempted to “capture the same unique feel on mobile devices”, 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 knowledge proved invaluable,” they said.
Producer Dongkyun Kye added, “At first, I was worried whether this kind of approach would be effective, but seeing how surprised and tense the players became at these moments made me feel relieved.”
