Roblox Murder Mystery 2 Guide: Values, Trading and Winning Tips

Murder Mystery 2 has racked up over 23 billion visits on Roblox [10] — making it one of the platform’s longest-running hits since developer Nikilis launched it back in 2014. The formula is deceptively simple: one Murderer, one Sheriff, everyone else trying to stay alive. But once you factor in weapon trading, a multi-tier rarity economy, and a community of experienced players who’ve been refining strategies for years, there’s a lot more going on beneath the surface.

This guide covers everything in one place: the three roles and how to play them well, the full weapon rarity ladder and what drives value, how to trade safely, how to use the crafting system, and the current codes situation — all updated for March 2026. If you’re just getting started with Roblox generally, our complete Roblox guide covers the platform fundamentals first.

How Murder Mystery 2 Works

Each round assigns one of three roles randomly to up to 12 players [10].

Innocent — The majority (up to 10 players per server). No weapons. Your job is to survive by evading the Murderer, identifying suspicious behaviour, and — if the Sheriff goes down — picking up the dropped gun to become the Hero for that round.

Sheriff — One player per round, armed with a gun. The only player who can directly eliminate the Murderer without being killed themselves. If you accidentally shoot an Innocent, your gun drops immediately for anyone to pick up.

Murderer — One player, armed with a knife. Your goal is to eliminate every other player before the round timer runs out. You can throw the knife for a ranged kill when needed.

The depth comes from the three-way psychology of it all: the Murderer needs to eliminate players without being identified; the Sheriff needs to identify the Murderer without revealing themselves too early; and Innocents need to stay alive while building enough information to either assist the Sheriff or pick up the gun themselves.

Gameplay Strategies by Role

Playing as the Innocent

Your biggest advantage is numbers. Stay close to at least one other player — the Murderer has a much harder time isolating and killing someone who’s never alone [6]. Watch for behavioural tells: players following a specific target across rooms, lurking near doorways, or consistently avoiding the main group. Experienced Murderers don’t rush, so the giveaway is often movement patterns rather than a visible knife.

If the Sheriff is eliminated and the gun drops nearby, grab it. You become the Hero, and your odds of winning improve significantly. That said, picking up the gun immediately makes you the Murderer’s new priority, so once you decide to do it, commit fully and stay mobile.

Keep moving throughout the round. Some perks in MM2 include X-Ray vision that lets the Murderer see through walls — standing still in one spot makes you easy to track and easier to kill [6].

Playing as the Sheriff

The hardest balancing act in MM2. You have the gun, but revealing your role too early turns you into the Murderer’s first target.

Don’t act like a Sheriff. Avoid obvious firing stances or following suspicious players too visibly. Move with the Innocents and gather reads before you act. I find that waiting until I have at least two independent observations pointing to the same player is usually the right threshold — one suspicious movement is too easy to misread.

When you do shoot, aim carefully. Hitting an Innocent drops your gun into the open, potentially into the Murderer’s hands. Use doorway angles and room edges to give yourself a sightline while keeping most of your body protected. Once you’ve identified the Murderer with high confidence, act decisively — every second of hesitation is another Innocent in danger.

Playing as the Murderer

Blending in at round start is non-negotiable for experienced players. Rushing kills in the first few seconds flags you immediately, and once the Sheriff has a confirmed position on you, the round is almost certainly over.

Work on separating targets from the group. Isolated players are exponentially easier to kill than someone standing next to two Innocents who’ll see exactly what happened. Use the knife throw against the Sheriff if they spot you — trying to close distance for a melee kill against a player with a gun is rarely the right play [6].

One crucial detail many beginners miss: your knife makes a "clink" sound audible to nearby players as you move. Experienced Innocents listen for this audio cue to locate you without seeing the knife. The Ninja perk eliminates this sound entirely [6] — if you’re playing Murderer seriously, Ninja is one of the highest-value perk choices you can make.

Weapon Rarity Tiers Explained

MM2 uses eight rarity tiers, from most common to most exclusive [1][4]. Understanding these is the foundation of everything in the trading economy.

Tier	Description
Common	Widely available; minimal trade value
Uncommon	Slightly harder to obtain; modest value
Rare	Notable difficulty; reasonable trade value
Legendary	Premium tier; genuine trade value
Godly	High-rarity; the standard unit of trading currency
Chroma	Animated colour variants sitting above Godly; highly sought after
Vintage	Older limited items; value driven by age and scarcity
Ancient	Rarest tier; often event-exclusive; highest values in the game

When someone says an item is "worth 3 Godlys", they’re using Godly weapons as the unit of exchange — the rough equivalent of a dollar in the MM2 economy [4]. Chroma weapons sit above Godly, distinguished by animated rainbow colour effects. Ancients are at the very top, and the rarest examples command extraordinary values: community tracking shows some Ancients priced in the hundreds of millions of in-game value units [4].

Trading in MM2: Values and the Demand Factor

Which Resources to Use

Two community sites have become the standard references for checking MM2 prices:

MM2Values — one of the original value tracking sites
Supreme Values — the more widely used resource among active traders as of 2025–2026 [7]

Check both before entering any significant trade. Values shift based on demand, game updates, and real trading activity in the community. A figure that was accurate last month may have moved.

Value vs. Demand — the Insight New Traders Miss

Raw value numbers only tell half the story. Every item also has a demand rating, typically measured on a scale from 1 to 10 [7]. A Godly weapon with high listed value but low demand (say, 2/10) is genuinely harder to trade than a Rare with modest value but high demand (9/10).

High-demand items move quickly at or near list price. Low-demand items need discounting or bundling to find a willing partner. The practical takeaway: when building a trade offer, weight it toward items the other player will actually want to use or re-trade — not just items with impressive numbers on paper. A bundle of popular mid-tier weapons often closes a trade faster than one flashy high-value piece nobody actually wants to hold.

Cross-Trading

Cross-trading — exchanging MM2 items for items from a different Roblox game — sits outside the official MM2 trading interface and carries meaningful risk. There’s no protection if the other party doesn’t follow through. Approach with serious caution [2].

Avoiding Scams: Five to Know

The MM2 trading community is active and largely fair, but scams do happen. These are the most common patterns [2][8]:

1. Fake Value Claims — Someone insists their item is worth far more than any value list shows, citing a "Discord price" or private list. Always verify independently on Supreme Values or MM2Values before accepting.

2. The Switcheroo — A trader displays a high-tier item, then quietly substitutes a similar-looking lower-tier one right before you confirm. Always read the full trade screen carefully — don’t rush the final step.

3. Middleman Scams — A "trusted" middleman offers to hold both players’ items during a cross-trade, then disappears with everything. Only use middlemen verified by a well-established community, and understand that unofficial middleman arrangements carry real risk regardless [8].

4. Sharking — The most common form: a player deliberately misrepresents an item’s value to profit from your lack of information [2]. The counter is knowing your own item’s value before entering any negotiation.

5. Too-Good-To-Be-True Offers — If someone is offering a Godly for a Common with no explanation, there’s almost always a setup coming. Genuine generosity doesn’t require a follow-up request.

General protection: record trades when possible. Never agree to trades outside the official Roblox interface — trust trades, item loans, and "I’ll pay you later" arrangements have no enforcement mechanism whatsoever [8][9].

The Crafting System: Salvage Into Better Weapons

MM2’s crafting station gives you something productive to do with weapons you’ll never use. Salvaging breaks a weapon down into raw materials — Shards and Metals — which you then spend to craft a new weapon, usually at a higher rarity tier [3].

What you can salvage: Only weapons labelled as "classic" are eligible. Salvaging a Common, Uncommon, Rare, or Legendary yields two Shards of that rarity. Godly weapons yield a specific amount of Shards that varies by weapon. The Seer is the exception: salvaging one produces 1 Godly Metal, which is used to craft a random painted Seer variant [3].

What you cannot salvage: Event knives, code-reward weapons, Ancient weapons, Vintage weapons, Xbox-exclusive weapons, and Season 1 weapons are all off-limits [3]. If you’re holding any of these, treat them as collectibles or trade assets only.

Is it worth doing? Yes, for clearing duplicate Common-through-Legendary weapons sitting idle in your inventory. The crafted result is random within the target rarity tier — you’re not guaranteed something high-value — so treat it as a low-cost upgrade path for stagnant inventory rather than a reliable route to Godly and above.

Codes: What’s Available Right Now

As of March 2026, there are no active codes for Murder Mystery 2 [5]. This has been the case for some time — the two most recent codes, FL4M and COMB4T2, have both expired.

How to redeem codes when they become available:

Launch MM2 and click the Inventory button on the left side of your screen
Find the EnterCode field at the bottom-right of the inventory screen
Type the code exactly as shown — MM2 codes are case-sensitive
Click Redeem to claim your reward

Where to find new codes: Follow developer Nikilis on X (formerly Twitter). Codes are announced there first and typically expire within days of release, so acting quickly when one drops is important.

Should You Open Crates? The Expected Value Reality

Coins collected during rounds can be spent on crates in the shop. The honest picture: the vast majority of crate results land at Common or Uncommon rarity. Godly and higher outcomes are possible but uncommon enough that crate opening is the least efficient path to high-value weapons.

The smarter approach is to use crate openings to build a broad base of lower-tier weapons, process the duplicates through the crafting station to improve rarity over time, and acquire specific high-value weapons through direct trading rather than relying on random drops. Save coins for consistent, planned openings rather than occasional splurges — the volume matters when you’re using crafting to process the results systematically.

Advanced Strategies

The Knife Sound Cue

This single detail separates new players from experienced ones more than almost anything else. The Murderer’s knife produces a "clink" sound audible to nearby players. Experienced Innocents use this audio tell to locate the Murderer without needing to see the knife directly.

As an Innocent: if you hear it, move immediately and alert anyone nearby. As the Murderer: the Ninja perk eliminates this sound, making you dramatically harder to track by ear [6]. It’s the highest-priority perk for anyone playing Murderer competently.

Map Awareness Principles

MM2 features multiple maps with varied layouts, but the same spatial principles apply across all of them:

Innocents benefit from open areas with multiple exit routes. Tight corridors and dead-end rooms are where Murderers accumulate easy kills.
Sheriffs want elevated positions or doorway angles — maximum sightline with minimum exposure.
Murderers want to funnel targets into enclosed spaces where the Sheriff can’t take a clean shot without exposing their own position.

Spending a few rounds on each map simply observing chokepoints and escape routes pays off quickly across all three roles.

Coin Routes

Each map has a fixed coin layout with a maximum of 40 collectible coins per round (50 with the Elite gamepass). As an Innocent, developing an efficient mental route through each map collects currency while keeping you visible to the group. You’re building your shop budget without wandering off alone into easy-prey territory.

The Hero Decision

When the Sheriff is eliminated, the gun drops. Picking it up is the right call when you know or strongly suspect the Murderer’s location and you’re confident in your aim. It’s the wrong call when you’re uncertain — becoming the Hero immediately makes you the Murderer’s top priority, and an unarmed mobile Innocent is often harder to eliminate than a newly-armed Hero telegraphing their position by picking up the gun.

Frequently Asked Questions

How many players are in a Murder Mystery 2 round?
Up to 12 players: one Murderer, one Sheriff, and up to 10 Innocents.

What happens if the Sheriff shoots an Innocent?
Their gun drops immediately and can be picked up by any player, including the Murderer.

Are there any active MM2 codes right now?
No — as of March 2026, no working codes exist. FL4M and COMB4T2 have both expired [5]. Follow Nikilis on X for the next announcement.

What’s the difference between Supreme Values and MM2Values?
Both track MM2 item prices, but Supreme Values has become the more widely-used reference among active traders. Check both to get a consensus price before any significant trade.

Can the Murderer win if only the Sheriff is left?
Yes. The Murderer’s objective is to eliminate every other player. Throwing the knife to disarm or eliminate the Sheriff is a valid win condition.

What’s the best starting point for trading?
Godly weapons are the standard unit of exchange. Build a small collection, learn their individual demand ratings, and start there before attempting higher-tier trades.

Is crafting worth doing?
Yes, for clearing duplicate Common through Legendary weapons. Results are random within the higher tier, but it’s far better than holding weapons you’ll never use or trade.

Wrap-Up

Murder Mystery 2 rewards patience and observation more than reflexes. The Murderer who blends in longest wins; the Sheriff who reveals themselves last survives longest; the Innocent who reads the room correctly is the hardest to catch. Add the trading economy on top — rarity tiers, demand dynamics, scam patterns — and there’s a genuine learning curve underneath the simple three-role premise.
