Trading is the real endgame of Murder Mystery 2. The rounds are fun, but the reason MM2 has held a huge player base for a decade is the item economy — and if you don't know how trading actually works, that economy is very good at separating you from your godlys. This is the full guide: mechanics, values, and the scams to watch for.
How trading works in MM2
Trading happens in the lobby, between rounds:
- •Walk up to another player and press the Trade button over their head (or open the menu → Trade → pick a player in your server).
- •Both players add up to 4 items each from their inventory.
- •Both players click Accept.
- •A final confirmation screen appears showing both sides one last time — both players accept again, and the trade executes.
That second confirmation screen exists for one reason: last-second swaps are the oldest scam in the game. A trader shows you a Harvester all negotiation long, then swaps it for a common knife right before you confirm. The final screen shows what is actually in the trade — read it every single time, item by item, before you hit accept.
Know what your items are worth first
Nothing else in this guide matters if you don't know values. MM2 has no in-game price display, so the community runs on value lists. Two numbers matter for every item: its value and its demand (an item with big value but no demand is hard to move).
- •Look up any item on our MM2 value list — every knife, gun and pet, sortable and searchable.
- •Browse by tier on the MM2 values index — Godly values, Ancient values, Chroma values and so on, each with a full ranked table.
- •Checking a specific deal? Put both sides into the MM2 value calculator and it scores the trade Win / Fair / Lose before you accept.
For scale: the top of the economy is the Ancient tier — Nik's Scythe sits at the very top, with items like Gingerscope and Traveler's Axe below it. The bulk of everyday trading happens in the Godly and Chroma tiers.
The 4-slot limit and split trades
Four items per side means big deals get split across multiple trades — and split trades are the single biggest scam vector in MM2. The promise is always the same: "accept this one, I'll send the rest in the next trade." Then they leave the server.
The rule that keeps you safe: be ahead (or even) after every individual trade. If a deal can't be structured so each trade stands on its own, the other trader is asking you to extend them credit. Don't.
The scams, catalogued
- •The last-second swap. Covered above — the final confirmation screen is your defence.
- •The overhype. "This just got buffed, it's going up" / "this is worth 3 Harvesters, trust me." Values aren't set by the person trading against you. Check the value list.
- •The split-trade promise. "Rest after this one." No.
- •The middleman who isn't. Someone offers to "hold both sides" of a cross-game or cross-item deal. MM2 has no official middlemen. Anyone volunteering is planning to keep the items.
- •Off-platform deals. Discord DMs offering to buy your inventory for PayPal Friends & Family, or "cheap godlys" for gift cards. Friends & Family has zero buyer protection — that's exactly why scammers insist on it. If you're going to buy items with real money, use a marketplace with card/PayPal buyer protection and a delivery guarantee — that's precisely what the BloxUltra MM2 shop is.

Building value from nothing
The classic ladder, still true in 2026:
- •Grind the seasonal events. Event knives and guns are free to earn and hold trade value after events end — several old seasonal items are Vintage-tier now.
- •Trade duplicates up. Two mid godlys for one better godly. Small, boring, consistent wins — checked in the calculator so you never take a Lose.
- •Ride demand, not value. A high-demand godly at fair value will climb faster than an overvalued "rare" nobody wants.
- •Skip the ladder entirely. If you just want a specific knife, buying it outright costs less than the dozens of trades it takes to climb to it. Every item in our MM2 shop is delivered in ~10 minutes.
Quick answers
Everything above, compressed: trade in the lobby, 4 items max, read the final screen, check every deal against the value list or calculator, never split-trade on a promise, and never move a deal off-platform to an unprotected payment method. Do that and MM2 trading is one of the most fun economies on Roblox instead of a donation to a scammer's inventory.
