Stranger Things stars Gaten Matarazzo and Noah Schnapp were among the names joining US chat show host Jimmy Fallon for a charity stream of Among Us.
The event marked Fallon's debut on the game-streaming platform Twitch, where he played the popular whodunnit multiplayer game Among Us.
Joining Matarazzo and Schnapp, who play Dustin and Will in Stranger Things, were YouTube stars Sykkuno, who has 2.64 million subscribers, Valkyrae, who has 3.29 million subscribers and Corpse Husband, who boasts 7.42 million subscribers.
Members of Fallon's house band The Roots also appeared, including Questlove, Tariq Trotter and Kirk Douglas, as well as a member of the game's development team Victoria Tran.
It was all in aid of Feeding America, a charity that supports food banks and soup kitchens in the US which has grown in prominence during the pandemic.
Viewers donated more than $17,000 (£12,290) to the charity, with Fallon offering to boost the amount to $25,000 (£18,000). At one point the stream topped 125,000 viewers.
Tweeting after the stream, Fallon said he got "CRUSHED", adding it was "soooooo fun". Clips will go out on Fallon's late night NBC chat show next week.
