MM2 Chroma Weapons & Effects Explained

Updated Jul 14, 2026

"Chroma" and "Effects" get mixed up a lot in Murder Mystery 2, but they're two completely different things. Here's the difference.

Chroma weapons

Chroma weapons are animated, rainbow-cycling variants of specific Godly weapons (Chroma Luger, Chroma Seer, Chroma Laser, and so on). They are:

  • Extremely rare to unbox — during Season 1, every box gave a chroma godly, which is why some exist at all.
  • Tradable, with real community value.
  • Still part of the Godly tier — Chroma is a variant label, not its own rarity.

There are roughly 35 chroma weapons in the game.

Effects

Effects are cosmetic particle and kill effects you equip on a knife — Radioactive, Flaming Knife, Musical, Heartify, Darkfire and more. They:

  • Are bought with Coins/Robux or won in events.
  • Are untradable (they have no trade value).
  • Change how your knife looks, not what it is.

The quick way to remember it

  • Chroma = a rare rainbow version of a godly weapon (tradable, valuable).
  • Effect = a cosmetic you slap onto a knife (untradable, personal).

If someone offers to "trade you an effect," they can't — effects can't leave your inventory.
