Complete Murder Mystery 2 Powers List
S-Tier Powers
X-Ray
Cost: 6,000 Coins or 800 Gems
Effect: See through walls for 4 seconds
Cooldown: 26 seconds
How it works: Reveals dead bodies, remaining innocents, the Sheriff, and the gun's location
X-Ray is arguably the most powerful perk available. The ability to track every player through walls gives you complete map awareness, making it nearly impossible for innocents to hide. This is especially valuable in larger maps where finding the last few survivors can be time-consuming.
Haste
Cost: 3,000 Coins or 400 Gems
Effect: Move 10% faster while holding your knife
Cooldown: Passive (always active when knife is equipped)
Haste provides a permanent speed boost with no cooldown or duration limit. The 10% increase may seem small, but it's incredibly effective for chasing down running targets. Since there's no activation requirement, you benefit from this power every second of the round.
A-Tier Powers
Ghost
Cost: 6,000 Coins or 800 Gems
Effect: Turn invisible for 5 seconds
Cooldown: 30 seconds
Limitation: Invisibility cancels immediately when you swing your knife
Ghost is a fantastic tool for approaching groups of innocents undetected. The ability to sneak up on the Sheriff and eliminate them without warning makes this a game-changer. However, the 30-second cooldown (increased from 20 seconds in a 2024 update) and the auto-cancel on attack require careful timing.
Sprint
Cost: 3,000 Coins or 400 Gems
Effect: 50% speed boost for 3 seconds
Cooldown: 30 seconds
Limitation: Leaves a visible trail while active
Sprint offers the highest burst of speed in the game, making it perfect for closing distance quickly. However, the visible trail alerts nearby players to your presence, reducing its effectiveness for stealth approaches. Despite this drawback, Sprint remains a top choice for aggressive players.
B-Tier Powers
Ninja
Cost: 1,000 Coins or 100 Gems
Effect: Your knife kills make no sound
Cooldown: Passive (always active)
Ninja is a budget-friendly option that prevents other players from hearing when you eliminate someone. This allows you to pick off isolated players without alerting the rest of the lobby. The low cost makes it accessible to newer players building their Coin reserves.
Sleight
Cost: 1,000 Coins or 100 Gems
Effect: Throw knives faster
Cooldown: Passive (always active)
Sleight reduces the delay between knife throws, significantly improving your effectiveness in ranged combat. This power shines in 1-on-1 situations against the Sheriff and when chasing down fleeing targets. For its low cost, Sleight provides excellent value.
C-Tier Powers
Trap
Cost: 1,000 Coins or 100 Gems
Effect: Place up to 3 invisible traps that freeze enemies for 4 seconds
Cooldown: 2 seconds between placing each trap
Limitation: Trapped players can still shoot you
Trap requires strategic planning to use effectively. Placing traps in narrow corridors or near the gun spawn can catch players off-guard. However, the inability to prevent trapped players from shooting limits its defensive utility.
D-Tier Powers
Fake Gun
Cost: 3,000 Coins or 400 Gems
Effect: Your knife appears as a gun for 10 seconds
Cooldown: 30 seconds
Fake Gun can fool inexperienced players into thinking you're the Sheriff, but this bluff rarely works against skilled opponents. If a real Sheriff is nearby, they'll shoot you on sight. The high cost makes this one of the least recommended purchases.
Footsteps
Cost: Free (default power)
Effect: See footprints left by Innocents and the Sheriff
Cooldown: Passive (always active)
Footsteps is automatically available to all players. While useful for tracking player movement, it provides no combat advantages and becomes less effective as footprints fade over time. It's a solid fallback option when you haven't unlocked other powers yet.

How to Earn Coins and Gems for Powers
Coins
Coins are the primary free currency in MM2. They spawn across the map every round, and you collect them by walking over them.
Coin farming tips:
Play as Innocent and focus on surviving—longer survival means more coins to collect
Free players cap at 40 coins per round; Elite Gamepass owners get 50
Join low-population servers for easier coin collection
Fill your coin bag to the maximum every round
Gems
Gems can only be obtained by purchasing them with Robux. The conversion rate is 1 Robux = 1 Gem across all bundles.
Gems allow you to purchase premium cosmetics, effects, and powers without grinding for Coins.
Best Powers to Buy First
If you're new to MM2 and want to maximize your effectiveness as the Murderer, here's the recommended purchase order:
1. Ninja (1,000 Coins) — Affordable entry point that silences your kills, allowing you to eliminate players without alerting others.
2. Haste (3,000 Coins) — The permanent speed boost is invaluable for chasing down survivors. This is arguably the best long-term investment.
3. Sleight (1,000 Coins) — If you prefer ranged combat, faster knife throws can turn the tide in Sheriff encounters.
4. X-Ray (6,000 Coins) — Save up for this powerhouse ability if you want complete map awareness and can't stand losing track of that last hidden innocent.
5. Ghost (6,000 Coins) — Excellent for stealth plays, though the higher cooldown requires careful timing.
The Fake Dead Emote: A Special Mention
While not a purchasable power, the Fake Dead emote deserves recognition as one of the most effective trick strategies in MM2. This Roblox UGC animation allows you to pretend to be dead, fooling the Murderer into ignoring you.
How to use it effectively:
Activate the emote in a visible location when the Murderer is nearby
The Murderer may assume you're already eliminated and move on
If the real Sheriff picks up the gun, you can coordinate ambushes
The Fake Dead emote costs 55 Robux and has become a popular tool for surviving rounds where you'd otherwise be an easy target.
Final Tips for Using Powers
Match powers to your playstyle:
Aggressive players should prioritize Haste and Sprint for chasing kills
Stealth-focused players will get more value from Ghost and Ninja
Strategic players can leverage X-Ray for map control and Trap for area denial
Test powers before committing:
If possible, try powers in private servers or during low-stakes rounds
Understanding a power's timing and limitations is essential for effective use
Don't overlook passive powers:
Haste, Ninja, and Sleight provide constant benefits without requiring activation
Passive powers are often more reliable than active abilities with cooldowns
Consider the Sheriff threat:
Powers that help you avoid or eliminate the Sheriff are especially valuable
X-Ray and Ghost excel at tracking and ambushing the Sheriff before they can shoot you
Conclusion
Investing in the right powers can transform your Murderer gameplay in MM2. While X-Ray and Ghost are the most expensive options, Haste offers the best overall value for its permanent speed boost. For budget-conscious players, Ninja and Sleight provide solid benefits at a fraction of the cost.
Start with Ninja or Haste, build your Coin reserves through consistent play, and gradually work toward the premium powers. With the right abilities equipped, you'll find yourself winning far more rounds as the Murderer.
