Season 4 — Mysterious Murderers

Season 4 is the headline content wave for Mysterious Murderers in 2026, arriving as the Roblox experience crossed 38M+ visits and 1.3M+ favorites. Granturismo Games framed the season around fresh presentation, new reasons to grind coins, and limited-time promo strings that reward loyal players who check Codes after each login. If you dropped the game after launch week in April 2026, Season 4 is the clean re-entry point — maps feel busier, lobbies peak around 10k concurrent users, and up to 12 players still cram into each murder-mystery round.

This page summarizes what Season 4 added, how to claim SEASON4, how the Free Chroma group milestone fits alongside seasonal codes, and where to go next on the wiki for roles, tier lists, and patch-level fixes.

SEASON4 promo code — 2,500 coins

The flagship Season 4 string is SEASON4, redeemable through Inventory → Enter Code on the left side of the screen. Verified redemptions grant 2,500 coins — one of the larger single-code coin bundles the developers have shipped, useful for buying melee skins, gun cosmetics, or saving toward featured shop rotations.

Redemption rules match other Mysterious Murderers codes:

• Case-sensitive — type SEASON4 exactly; lowercase letters fail.
• One claim per account unless Granturismo explicitly re-enables the promotion.
• Fresh server helps if Inventory lags after a patch; rejoin if the Enter Code button stays greyed out.

Always confirm SEASON4 is still active on Active Codes before you share it in Discord. Seasonal strings can expire without a public countdown. If the client returns “invalid” or “expired,” check Expired Codes and skim Patch Notes for replacement promotions.

Themed content and presentation

Season 4 pushes extend beyond a single coin code. Players reported:

• Updated lobby presentation and seasonal framing that makes new sessions feel distinct from launch-month queues.
• Cosmetic drops tied to the season theme — knives, hammers, and gun skins that show up in kill cams and post-round showcases.
• Map and mode polish that keeps rounds readable when twelve players stack in choke points — important for both Sheriff reactions and Murderer stealth paths.

Exact asset names rotate with shop inventory, so treat our Tier List as the living reference for which Season 4 gear punches above its rarity in live lobbies.

Free Chroma and the 50k group milestone

Parallel to Season 4 codes, Granturismo ran a community milestone: when the official Granturismo Games Roblox group reached 50,000 members, eligible players could claim Free Chroma through the standard Inventory reward flow. This is not the same as typing SEASON4, but it landed during the same growth spike that Season 4 marketing rode.

If you missed the milestone window:

1. Join the Granturismo Games group on Roblox anyway — future milestones may repeat the pattern.
2. Open Inventory after joining; group perks sometimes delay a few minutes.
3. **Cross-check Codes for strings like FR33C4ROMA or community variants — status varies, so verify in-game.

Free Chroma is cosmetic flair; it does not replace learning Sheriff aim or Innocent hiding spots from Getting Started.

August 2026 context

Season 4 rolled out alongside August 2026 maintenance and balance passes documented in Patch Notes. Visit counters climbing past 38 million mean more novice Murderers and Sheriffs in matchmaking — mechanical fundamentals matter more than raw cosmetics.

Peak concurrency near 10k also implies slightly longer queue times during evenings (UTC-5/US afternoons). Party up with friends to guarantee all 12 slots fill on private servers if you practice role strats.

How Season 4 compares to earlier seasons

Mysterious Murderers launched 15 April 2026 with launch hype codes (UPDATEHYPE, ICE, and others now expired on Expired Codes). Season 4 follows that opening burst with sustained retention focus:

Era	Focus	Example reward
Launch month	Hype + tutorial influx	UPDATEHYPE (expired)
Mid-2026 weapon waves	Themed melee/guns	OCEAN, LAVA, FUTURE (see Codes)
Season 4	Coin bundles + seasonal UI	SEASON4 → 2,500 coins
Group growth	Community milestone	Free Chroma at 50k members

Season 4 is less about teaching controls — that remains Getting Started — and more about giving veterans a coin injection and fresh cosmetics to chase.

Recommended checklist for Season 4

1. Redeem SEASON4 if still active (2,500 coins).
2. Claim Free Chroma if you qualify via the 50k group milestone.
3. Read Patch Notes for weapon tuning after August updates.
4. Refresh loadouts on Tier List before ranked-style sessions with friends.
5. Avoid post-patch scripts — see Scripts for ban-risk disclaimers; many MM2 loadstrings break after Season 4 UI changes.

Role-specific Season 4 tips

Murderer players: new cosmetics do not buff damage — use coin savings for knives with quieter animations if the shop offers them. Sheriff players: coin bundles help buy crosshair-friendly gun skins that reduce visual clutter. Innocent players: spend on emotes or flair only after you can consistently survive mid-round; positioning lessons in Getting Started beat any skin.

Staying updated after Season 4

Seasons end; codes expire. When Granturismo teases Season 5 or a mid-season hotfix, this page will cross-link the new hub entry on Updates and any replacement promo strings on Codes. Turn on Roblox notifications for the game page if you want first-party banners the moment they publish.

Season 4 proves Mysterious Murderers is more than a launch-week novelty — 38M+ visits and 1.3M+ favorites show a murder-mystery audience that stayed after the initial TikTok wave. Claim SEASON4, grab Free Chroma if you can, and play the season officially rather than risking accounts on broken exploit hubs.
