The Alien Key is a special event item from the 2025 Halloween Event in Murder Mystery 2. It was designed to unlock the Halloween Box during that event. Since the event has ended, the Alien Key is no longer available to obtain.
What Is the Alien Key?
The Alien Key is a miscellaneous item with a futuristic design. The key features a dark neon end with light green neon accents, all bordered by a metallic frame that gives it a sci-fi appearance. Its sole purpose was to unlock the 2025 Halloween Box during the Halloween Event 2025.
How to Get the Alien Key
The Alien Key is no longer obtainable as the 2025 Halloween Event has concluded. During the event, it was earned as a tier reward through event progression.
If you weren't playing during the event, you won't be able to get this key now. The item is untradeable, so other players can't give it to you either.

Before the Alien Key, the game featured several other event keys with different themes, including the Vampire Key, Traveler Key, Pumpkin Key, Skeleton Key, and Reaver Key.
