The 2021 Arcane launch's iconic crossovers with Fortnite, PUBG Mobile, and Among Us redefined gaming events.

It's 2026, and I still get goosebumps thinking about the absolute insanity that was the Arcane launch back in November 2021. As a long-time gamer and League of Legends fan, I was already hyped for the Netflix series, but Riot Games decided to go completely nuclear with their promo campaigns. They didn’t just drop some skins in their own games—they invaded the biggest battle royale titles and even the social deduction sensation of the pandemic era. Yes, I'm talking about the legendary triple crossover with Fortnite, PUBG Mobile, and Among Us. It was a masterclass in gaming cross-pollination, and even five years later, collaborations rarely hit this hard.

Let’s set the stage: Arcane was set to debut on November 6th, 2021, and Riot went all out with the RiotX Arcane event. We saw in-game extras across their entire portfolio, a global premiere on Twitch, and literal skyscraper-sized marketing at the Burj Khalifa in Dubai and Times Square in New York. But the real magic happened when they reached beyond Runeterra and planted their champions into worlds where building, looting, and emergency meetings were the norm.

🔥 The Among Us Cosmicube: A Smol Bean x Zaunite Collab

The first crossover that caught everyone off guard was with Among Us. Innersloth, the little indie team that could, announced their first-ever in-game partnership with the tweet "BEAN CHAMPIONS!!!" and I couldn't believe my eyes. We were getting an Arcane Cosmicube, dropping on November 12, 2021. The cube was packed with cosmetics that transformed our adorable murder beans into mini representations of Vi, Caitlyn, Jinx, and Jayce. I remember frantically completing tasks just to unlock that Jinx-inspired hat with the iconic blue braids. The fusion of the cute, colorful spaceship atmosphere with the gritty Piltover/Zaun aesthetic was so absurdly brilliant that it instantly became a fan-favorite. Even today, when I see an Among Us mod showcase on Bilibili, someone always brings up the Arcane Cosmicube as the gold standard for how to do a collab without breaking the game’s identity. Truly, it was a match made in chaotic heaven. ✨

🏆 PUBG Mobile: Choosing Between Piltover and Zaun in Erangel

Then there was the heavy-hitter. On November 16th, PUBG Mobile's version 1.7 update rolled out, and it brought the Arcane universe crashing into the battlegrounds. This was the first partnership between Tencent’s PUBG Mobile publishing team and Riot Games, and they did not hold back. Four main characters—Jinx, Vi, Caitlyn, and Jayce—became playable cosmetics, but it was more than just skins. The entire game mode shifted: you could officially join Team Piltover or Team Zaun, and new areas and gameplay mechanics inspired by the show appeared on Erangel.

I vividly recall dropping in Pochinki and finding a Hextech gadget that gave me a temporary speed boost, and being torn between my love for Vi’s gauntlets and my chaotic Jinx energy. Vincent Wang, Head of PUBG Mobile Publishing at Tencent Games, said at the time that “Runeterra is one of the most beloved universes in gaming, and to be able to bring that magic to PUBG Mobile... is an amazing opportunity.” And it truly was. The collaboration didn’t just slap on textures; it reimagined the battle royale experience, letting you feel like a Piltover enforcer or a Zaunite renegade. As a player, it gave my squads a whole new layer of role-playing banter. "I'm playing Caitlyn, I'll snipe from the hill—just like a proper Sheriff!" That kind of immersion was priceless. 🔥

🎨 Fortnite: Jinx Drops from the Battle Bus

But if you really wanted to channel pure anarchy, Fortnite was the place to be. On November 4th, 2021, the Fortnite team tweeted "We can’t wait to see Arcane Jinx jump off the Battle Bus!" and I instantly loaded up my V-Bucks. The crossover brought Jinx as a fully playable Outfit, complete with the Pow Pow Crusher Pickaxe, Jinx’s Dream Monkey Back Bling, and a bunch of themed loading screens and sprays. The bundle was an instant classic. I spent countless hours running around the island with her pigtails flowing, spraying Jinxed tags all over Pleasant Park, and emoting with the Playground (Instrumental) Lobby Track.

What made this even more groundbreaking was the simultaneous deal between Riot and Epic Games: a selection of Riot’s own PC titles—League of Legends, Teamfight Tactics, Legends of Runeterra, and Valorant—launched on the Epic Games Store. Brandon Miao from Riot XP commented on how they admired Fortnite’s commitment to bringing players content that enriches the experience both in and out of game. It was a two-way street of respect, and it paid off massively. Even now, whenever I see a Fortnite survey skin concept inspired by a new animated show, I think back to Jinx and how she set the bar so high. 🚀

🕹️ Why This Still Matters in 2026

Looking back, the Arcane crossovers in 2021 weren’t just marketing stunts—they were cultural events that bridged communities. PUBG Mobile players got curious about League of Legends lore, Fortnite kids discovered Jinx’s tragic backstory, and Among Us casuals suddenly became Arcane superfans. The synergy was flawless, and it showed that when two (or three!) games genuinely respect each other’s creative DNA, the result is pure magic.

Today, multiverse collaborations are almost expected in live-service games, but the Arcane event remains a benchmark. It combined timely releases, deep integration, and authentic fan service. No wonder we still see clips from that era pop up in compilation videos and nostalgic streams. As a player who experienced it all firsthand, I can confidently say that November 2021 was a fever dream of gaming goodness. Riot didn’t just launch a show; they launched a new way for games to talk to each other. And for that, this bean will always be Team Piltover... with a little bit of Zaunite chaos mixed in. 😉
