UK studio Salix Games and creative agency Liquid Crimson are teaming up for Overdue Exorcism, a one-night-only, live table RPG performance to support charity SpecialEffect.
Taking place on October 3, 2025, the Overdue Exorcism charity stream will be guided by game master Natalie Walker, who voiced Nambi Ghimi in Lego Star Wars: The Skywalker Saga and Alice Blague in Astrologaster.
Winter will be joined by a host of acclaimed voice actors, including Billie Fulford-Brown (Sophie in Clair Obscur: Expedition 33), Dave Jones (Halsin in Baldur’s Gate 3), Kathyrn Vinclaire (who provided voice work for Conan Exiles and Warhammer Soul Arena), and Kit Harrison (Sawada in Genshin Impact). There will also be special guest cameos.
The strean has a £10,000 fundraising goal, and you can watch it on SpecialEffect’s Twitch channel from 6pm to 10pm BST on October 3, 2025.
Those who tune in will be able to unlock fundraising milestones that “force the cast into wild accents, musical interludes and full-blown possession swaps.”
There will also be viewer-triggered perks that let fans “inflict chilli-chocolate roulette, demand dance-offs or make their favourite actor read romantic or horror poetry in-character, straight to camera.”
“We’re not here to play it safe – we’re here to summon ghosts, break rules and blow the doors off tabletop streaming,” said Lauran Carter, comms director at Liquid Crimson.
“It’s theatre meets games meets rock show – and it’s all for SpecialEffect!”

The Overdue Exorcism stream is part of Special Effect’s One Special Day initiative, which aims to “level the playing field for physically disabled gamers.”
On the same day as the stream, SpecialEffect is hosting its One Special Walk fundraising event, which will see those who sign up walking 25km across Greater London, from the London Stadium all the way to Wembley.
The charity is also hosting a Steam sale, which runs from September 11, 2025, to September 18, 2025.
This is the ninth consecutive year SpecialEffect’s One Special Day has taken place, with last year’s initiative raising over £600,000.
“We couldn’t be more thankful for everyone who has put their time into this incredible stream, and we can’t wait to see what shenanigans take place on October 3 as part of One Special Day in support of our work!,” said Paige Harvey, gaming community manager at SpecialEffect.
“In our eyes, this event is already a natural 20!”
