Innocent
Stay alive and identify the Murderer.
Keep an escape route in view. If you witness an attack, get away before trying to warn others; a suspicious outfit alone is not evidence.

Beginner
Your first round in MM2
Murder Mystery 2 is Nikilis’s round-based survival game on Roblox. Most players try to survive while a hidden Murderer hunts them and a Sheriff tries to stop the attack. Between rounds, collecting and trading knives gives you a separate long-term goal.
Join Nikilis’s game
Use the official Roblox link above. In the lobby, vote for a map or wait for the next round. Read your assigned role when the round begins.
Play for your role’s objective
As Innocent, survive and notice attacks. As Sheriff, identify the Murderer before shooting. As Murderer, eliminate the other players while avoiding the Sheriff.
Learn a route before chasing loot
Try to remember one connected path through the map. Collect coins when the route is clear, but leave a pickup behind if reaching it would trap you. Seasonal pickups may replace ordinary coins.
Use the next lobby break
Check your inventory and choose a collection goal. For the next round, practice one improvement: spotting the knife earlier, keeping an exit open or taking a calmer shot.
Roles & tacticsCompare Innocent, Sheriff and Murderer goals, plus what happens when the Sheriff drops the gun.
Roles and round tactics
Sheriff
Use your gun to stop the Murderer.
Leave room to aim and wait for a clear target. Identify the Murderer before firing; do not shoot just because someone follows you.
Murderer
Eliminate the other players without being shot.
Watch the Sheriff’s sightline before revealing your knife. Use turns and cover to approach instead of running straight through an open firing lane.
What if the Sheriff falls?
An Innocent who picks up the dropped gun becomes the Hero and can try to stop the Murderer. Check the area before approaching it: a visible gun can draw several players into the same dangerous spot.
These are the standard round roles; special modes can use different rules.

How to trade in MM2
The community trading reference lists level 10 as the minimum requirement. Select a player in the player list, choose Trade and wait for them to accept. Add the items you want to exchange, inspect both offers and accept only when the displayed trade is the one you want.
Weapons, pets and some miscellaneous items can be traded; effects, emotes and radios cannot. Compare the exact item name and variant. Rarity, demand and availability can differ between two items in the same tier.
