Riot Games unveiled the third and final phase of its RiotX Arcane event, ‘Undercity Nights’, featuring a live Secret Cinema League of Legends experience and other game updates.
A host of activities will take place from November 14th to 20th 2021 to drum up interest in Arcane, the Netflix animated League of Legends show, as it approaches its season finale.
On November 19th, Undercity Nights will preview a Secret Cinema live experience, called Arcane: Enter the Undercity, in Los Angeles. The full show will run from November 21st to December 19th 2021.
This Secret Cinema event features an original story set within the lead up to the Arcane finale, where fans will be able to choose their undercity faction and challenge each other for control of the shimmer supply. The real life experience will be filled with twists and turns, puzzles, and unexpected encounters with characters from the show, with multiple endings based on who comes out on top (and how).
Secret Cinema is of course a London-based entertainment company that specialises in immersive film and TV events, for example it has arranged live Secret Cinema events for the likes of Back to the Future, Star Wars, Ghostbusters and more.
Esports News UK reached out to Riot to see if a League of Legends Arcane Secret Cinema event may come to the UK or other regions in the future, and a spokesperson told us it’s US-only at the moment, and we’ll hear more if this changes.
On November 19th and 20th, fans and players across Riot’s global community are invited to celebrate the Arcane season finale via the Undercity Nights event being broadcasted live from Los Angeles.
Physical and digital attendees will experience live entertainment, a charity tournament featuring prominent community members playing Riot’s games, and more. Arcane’s final three episodes will be available on Netflix globally and Tencent Video in China at 8am GMT on November 20th.
“Undercity Nights is a celebration of the community, competition, and games at the core of our IP. We hope that players who have been with us since the beginning, and those just discovering us through Arcane, enjoy the finale and festivities.”
Sarah Schutz, Riot Experience
The event will include the first-ever Riot Gauntlet, a two-day charity tournament across a number of Riot’s games with a prize pool of $100,000 to be donated to the winning teams’ charities of choice.
Team captains will choose from a group of prominent community members from around the globe to team up and compete in a selection of Riot’s games, culminating in a finale match pitting the team captains against a team of Riot Games developers on November 20th.
“Undercity Nights is a celebration of the community, competition, and games at the core of our IP,” said Sarah Schutz, Head of Riot Experience (XP). “We hope that players who have been with us since the beginning, and those just discovering us through Arcane, enjoy the finale and festivities.”
The following Arcane-inspired content and product features will also be going live across Riot’s games during Undercity Nights from November 14th to 20th:
