Man, let me take you back. It’s 2026 now, and I’m still low-key nostalgic about the wild ride that was Among Us in its prime. But there’s one moment that really sticks with me—the first-ever official crossover: Arcane x Among Us. No cap, that collab was a big deal. It dropped back in November 2021, right when Arcane was taking over Netflix and everyone was obsessed with Jinx and Vi. I remember hopping into a lobby and seeing crewmates running around with Heimerdinger’s hair or Caitlyn’s hat, and thinking, “This is lit.”
At the time, I was grinding Among Us like crazy. The Cosmicube update had just landed, adding a battle-pass-style system where you’d earn Pods and unlock cosmetics along a branching tree. The Arcane Cosmicube was the shiny new toy—and it was limited. You could only buy it until December 31, 2021. After that, poof, it vanished from the store. I snagged it on the last day, feeling like a total boss. 😎
Here’s the thing: once you bought it, you kept it forever. So even now, in 2026, I can still flex those champion skins. But the Arcane Cosmicube itself? Gone. If you missed it, you’re out of luck. That’s the bittersweet part of limited-time events—they’re special because they’re fleeting.
Let me break down what was inside, because it was a treasure trove for League of Legends fans:
| Cosmetic | Champion | Type |
|---|---|---|
| Heimerdinger Hat | Heimerdinger | Hat |
| Jayce Visor | Jayce | Visor |
| Caitlyn Top Hat | Caitlyn | Hat |
| Vi Gauntlets | Vi | Skin |
| Jinx Hair | Jinx | Hat |
| Poro Pet | (Heimerdinger’s pet) | Pet |
That Poro pet? Adorable. I’d waddle around the Skeld with that little fluffball trailing behind me, and honestly, it made being a crewmate way more fun. Of course, it didn’t change gameplay—purely visual, just like every other Cosmicube. But who cares? Looking fresh while doing tasks is half the battle.
The collab was a big deal for Among Us because it was the game’s first official in-game partnership. Innersloth had never done anything like it before. And it made sense—Arcane was a Riot Games production, and League of Legends champions like Jinx, Vi, and Caitlyn were already fan favorites. Seeing them pop up in a social deduction game was a crossover I didn’t know I needed.
But here’s the kicker: in 2026, Arcane has had its second season (which dropped in late 2024, and yes, it was as emotional as everyone said). The hype has settled, but the Among Us collab remains a time capsule. It was a moment when two massive gaming worlds collided, and for a few weeks, you could vote out your friends while dressed as a hextech inventor. That’s peak gaming right there.
Would I love to see another collab? Absolutely. Innersloth hinted back then that more partnerships could happen, but so far, nothing has topped the Arcane crossover for me. Maybe one day we’ll get a Valorant or Arcane Season 2 Cosmicube. But for now, I’ll just keep rocking my Jinx hair and remember the good old days. If you were there, you know. If you weren’t… well, that’s sus. 😉
Anyway, the Among Us x Arcane Cosmicube is a reminder that limited-time events can be a real FOMO trap, but they also create legendary memories. And in 2026, with the game still going strong on multiple platforms, I’m just glad I was part of it. No cap.
