The three roles and what each one needs

The Murderer (or Assassin, depending on the mode) hunts players with a knife, either thrown or used directly at close range.

The Sheriff carries a gun and is the only player who can end the round by eliminating the Murderer.

Innocents have no weapon at the start - their job is to survive, and their path to winning runs through the Sheriff staying alive or a dropped gun being picked up.

Guns have been present in all game modes except Assassin, and the wiki is blunt about their importance: outside of time, they have been the only way for Innocents to survive and win.

How the knife works

Knives are melee weapons, and the category is broader than the name suggests: the Saw, Candy, Battle Axe, Pixel, Spider and Clockwork are all considered knives.

You can throw the knife at a target or use it directly, which means the Murderer's approach changes with distance and cover.

Controls differ by platform, with separate computer, mobile and console schemes for the same actions.

Because throwing exposes your position less than closing distance, knife choice is partly about how visible you want to be.

How the gun works

To use a gun, hold it out and click or tap a target, which creates a trail from the gun to the clicked point along with revolver and reload sound effects.

Shooting the Murderer produces confetti from the body and declares victory for the Sheriff and Innocents.

Shooting an Innocent kills both the Sheriff and the Innocent - the single most costly mistake in the game.

When the Sheriff dies, the gun floats over the spot with a green particle effect indicating it can be picked up; standing on it lets an Innocent take the gun and become a Hero.

Weapons: where they come from

Unboxing is the main route: boxes cost 1,000 coins, a key purchasable for 125 gems, or 100 gems.

Crafting uses salvaged weapons to produce new ones, which is the route that turns duplicates into progress.

Holiday events run their own unboxing pools for Christmas and Halloween weapons.

Trading with other players is the fourth route, and limited unique weapons - trophies - come from finishing in the top 100 on an event leaderboard.

Understanding value before you trade

Each knife and gun has its own value, and higher tiers generally mean more value - but not always.

Very rare non-godlies can outvalue some godlies depending on rarity, and high-value knives below godly tier are called collectibles.

Collectibles can be several times rarer than godlies, which makes them the main trap for new traders.

There are 8 rarity types and 2 item types - the latter being items with in-game abilities.

Holiday weapons sit on a separate inventory page from classic and Season 1 weapons and are usually worth more because their supply ended with the event.

Playing better in your first sessions

If you are the Sheriff, never fire into a crowd - the cost of hitting an Innocent is losing both of you at once.

If you are an Innocent, position near the Sheriff but not stacked on them, so a knife throw cannot remove both the gun and you.

If you are the Murderer, remember that thrown knives leave less evidence of your route than a direct attack.

Track the gun: once the Sheriff is dead, the floating weapon is the round's turning point, and being closest to it decides who becomes the Hero.

Treat every trade as a value negotiation, not a rarity one - check the community tier list rather than assuming 'godly' means 'better'.

Rarity, holiday weapons and round awareness

There are 8 rarity types in Murder Mystery 2, plus 2 item types - items with in-game abilities.

Holiday weapons sit on a separate inventory page from classic and Season 1 weapons and are usually worth more because they were only obtainable at Christmas or Halloween.

Limited unique weapons, known as trophies, come from finishing in the top 100 on an event leaderboard and never appear in box odds.

Crafting from salvaged weapons is the one conversion that turns duplicates into something new rather than another gamble.

In a round, awareness matters more than reflexes: know where the Sheriff is, know who has died, and move when the gun drops.

As an Innocent, standing next to the Sheriff makes you a target too - spacing is what keeps the gun in play.
