Gaming companies around the world are once again pledging their support to UK-based accessibility charity SpecialEffect.
Returning for its fourth year on October 4, One Special Day will see over 50 game companies donating a day of their income from game sales, or organising special fundraising events.
Set to be the biggest day so far, this year sees Sega, Codemasters, Jagex, Zynga, Rare, Rocksteady and dozens of others pledge their support.
Since the first One Special Day in 2016, developers and gamers around the world have helped to raise over £900,000 for people with disabilities.
Over the years, the funds have helped develop bespoke set-ups that allow people with disabilities to play games, such as EyeMine, software for controlling Minecraft with the eyes.
"We're overjoyed with the response again this year and very grateful to our One Special Day partners," said SpecialEffect CEO and founder, Dr Mick Donegan.
"The day unites the worldwide games industry and their fantastic communities of gamers because they all understand what incredible work we're doing here.
"SpecialEffect has a profoundly positive impact on the lives of disabled gamers and events like One Special Day play a huge role in enabling us to reach more in the coming year."
Rich Eddy, director of communications at Jagex, added "Our RuneScape community has celebrated SpecialEffect's incredible work for many years, so there was no question that Jagex would be a proud supporter of this year's event and play a big part in One Special Day.
"By putting the fun and inclusion back into the lives of those with physical disabilities to play video games, the work of SpecialEffect really levels the playing field."
