I still remember the night I opened Among Us and saw a crewmate wearing what looked suspiciously like Heimerdinger’s moustache. I was a regular player — not a streamer, not a dataminer, just someone who loved the loop of tasks, vents, and emergency meetings. The Arcane collaboration between Riot Games and Innersloth felt like a strange little gift: a Netflix animated series about League of Legends characters was suddenly dressing up my favorite social-deduction game. In late 2021, that was the crossover I did not know I needed.
A Cosmicube With A Story
The collaboration arrived through Among Us’ first-ever Cosmicube progression system. Unlike a simple item shop drop, Cosmicubes were a battle-pass-like track: I played matches, earned XP, and watched cosmetics unlock. To start earning the Arcane skins, I had to purchase the Arcane Cosmicube first. That detail mattered because it turned the event into a small commitment. I remember grinding tasks while silently judging everyone who called a meeting too early. 😅
The event ran until December 31, 2021. There were no gameplay bonuses, no extra speed, no secret vision buffs. The items were purely cosmetic. That was part of the charm: a Jinx-haired crewmate could still be the imposter, and a Heimerdinger-suited scientist could still be completely sus.
The Loot Table I Still Remember
The Arcane Cosmicube let players unlock a surprising pile of character pieces. I made it my personal mission to collect as many as I could before the window closed.
| Character / Theme | Cosmetics |
|---|---|
| Heimerdinger | Hair, Moustache, Suit, Poro |
| Enforcer | Helmet, Armor |
| Caitlyn | Cap, Uniform |
| Vi | Hair, Clothes |
| Jinx | Hair, Goggles, Clothes |
| Jayce | Hair, Council Suit |
| Other Arcane touches | Chomper, Claggor’s Goggles |
Seeing that list in 2026 is a nostalgia trip. Heimerdinger’s Poro was adorable. Claggor’s Goggles were a deep cut for fans. Chomper was the kind of weird little cosmetic that made Among Us feel playful. I wore Vi’s hair and Jinx’s goggles in the same session once, mostly to confuse people. It worked. 🚀
Why The Crossover Hit Different
At the time, Arcane was releasing weekly on Netflix, and it was already proving to be a hit for Riot Games. It was one of Netflix’s best-rated original shows ever, and the crossover energy was everywhere. Arcane also crossed over with PUBG and Epic Games, but Among Us was the one that felt most personal to me. In a game built on lies, paranoia, and tiny cartoon astronauts, dressing as Jinx or Caitlyn was absurd in the best way.
I loved that the collaboration did not try to turn Among Us into an action game. It stayed cosmetic. The core loop remained: do tasks, watch cameras, accuse your friends, and feel briefly guilty when you were wrong. The Arcane skins just added a layer of fan theater. A Heimerdinger moustache bobbing through a spaceship corridor is funnier than it has any right to be.
Looking Back From 2026
By 2026, Arcane is a complete, acclaimed story, and the original Among Us crossover is a closed chapter. The Arcane Cosmicube ended on December 31, 2021, and as far as I know, it never came back. That makes the event feel like a time capsule: a moment when two very different fandoms overlapped, and players like me got to run around as our favorite characters while accusing each other of venting.
Limited-time cosmetics are strange ghosts. They exist in screenshots, in old clips, and in the memory of players who happened to be there. I cannot log in now and buy the Arcane Cosmicube, and that is okay. The fun was never in owning every item. The fun was in the shared silliness: a lobby full of Vi hair, Jinx goggles, and Heimerdinger moustaches, all pretending to trust each other. 🛸
If I could go back, I would still grind those XP bars. I would still wear the Poro. I would still vote for the crewmate with the Enforcer helmet, because honestly, that helmet looked suspicious. And I would still smile at the memory of Arcane and Among Us colliding — a brief, bright crossover that made the spaceship feel a little more magical.
