Director claims players have “misunderstood” the filter in wake of reported migraines and vertigo


Two characters battle in Tekken 8 with the game's colourblind mode filter turned on, replacing their appearance with horizontal and vertical black and white stripes

The director of Tekken 8 has responded after a video of the upcoming fighting game’s colourblind mode was reported to have caused migraines and vertigo among players, with accessibility experts expressing their worries that the filter could cause even more serious side effects among those with epilepsy and other photosensitive conditions.

A video of the filter was shared around social media last week, showing two fighters replaced by stark white and black lines – vertical for one character, horizontal for the other. The two models were then placed against a monochrome stage background. As the characters move around and perform attacks, the lines move with them.

While the original post praised the filter for offering a colourblind mode, a number of players quickly reported that viewing the eye-grating filter had given them migraines and caused sensations including vertigo. (Needless to say, please do not watch the video if there is any chance you are at risk from a photosensitive reaction.)

Among those who raised concerns was EA’s game accessibility lead Morgan Baker saying that the video had “induced an aura migraine for me”.

While tolerance for the strobing effect can seemingly vary by person, the worry is that it may trigger even more serious side effects in those with photosensitive epilepsy and other conditions. Accessibility expert Ian Hamilton echoed Berg’s worries, saying that “the intent was good and the technology is good”, but nevertheless urging Tekken 8 director Katsuhiro Harada to delete the filter before the game’s full release.

“It cannot be present at launch as it may hospitalize players (or worse), in the same way as the infamous Pokémon episode,” Hamilton wrote, referencing a 1997 episode of the Pokémon TV series that inadvertently caused hundreds of epileptic seizures in children.

“The way that people find out they’re prone to seizures, which can be fatal (SUDEP), is by having one. The intent, behind it, i.e. separating characters by something other than hue, is fantastic. But this isn’t the way to achieve that.”
