About the Xeno (Effect)
The Xeno effect is a Common-tier knife visual enhancement in Roblox MM2, featuring a subtle purple electricity aura around your weapon. Originally available during the 2025 Halloween Event, this effect gives knives a futuristic, sci-fi appearance in Murder Mystery 2. While it lacks complex animations, its clean electric design makes it a popular choice among players looking for simple cosmetic upgrades.
Trading Tips
As a Common effect, Xeno has lower trade value compared to higher-tier effects. It's best used in combination with other Common-tier items or as a small addition in larger trades. Look for players collecting Halloween-themed effects or those building Common-tier collections.
