Twenty-four days after Summer Event 2026 ended, Murder Mystery 2's September 16 Supreme batch repriced 19 rows — Chroma Beach Set led drops at −300, Chroma Constellation slipped to 31,000 at demand 7, and Celestial Set printed its first red value line since losing demand 6.

Last updated: September 16, 2026
Twenty-four days after Summer Event 2026 closed, Murder Mystery 2 traders are unwinding live-event chroma faster than Godly shelves are rotating. The September 16, 2026 Supreme batch logged 19 repriced rows on MM2 Calculator’s value changes log: Chroma Beach Set led with −300 to about 2,850–3,050 at demand 5/10, Chroma Constellation Gun printed −1,000 to 31,000 while still at demand 7/10, and Celestial Set finally showed a red value line (−150 to ~5,600) two days after demand fell 6 → 5. On the same tape, Raygun added +100 to roughly 1,900–1,950 at demand 6/10, and Chroma Blizzard Set / Chroma Blizzard Gun each added another +250 at demand 6/10. The homepage sync also flagged Chroma Traveler's Gun at −5,000 to about 160,000.
Quick answer: Chroma Beach Set fell 300 to the 2,850–3,050 range, Chroma Constellation Gun slipped to 31,000, and Celestial Set printed its first red line after losing demand 6. Raygun, Alien Set, and Chroma Blizzard stayed on the greener side of the batch.

September 16 at a glance — Day 24, beach OUT and constellation cap
Summer Event ended on August 23, 2026. Supreme has repriced on a rough one- to two-day cadence since then. September 14 was a 24-row batch (Raygun demand flip, Celestial demand exit); September 15 was mostly a site sync day (Traveler's −5K). September 16 brought a fresh batch again — smaller in row count, but loud on seasonal chroma.
| Lane | September 16 read | Demand / stability |
|---|---|---|
| Post-event chroma OUT — Beach pack | Chroma Beach Set ~2,850–3,050 (−300); homepage also flags Chroma Beachy ~1,400 (−150, ~−9.7%) | 5/10 · Underpaid For on set page |

| Playbook follow-through — Celestial cluster | Celestial Set ~5,600 (−150); Constellation Gun −100 in same batch | 5/10 on set · stable tag on item page |

Chroma Beach Set −300 — post-Summer chroma finally breaks
Beach-themed chroma looked sticky for weeks after Summer Event ended: Chroma Beach Set even printed small greens in early September before demand stepped down to 5/10. The September 16 batch is the first large red line on the set in this post-event window — −300 from about 3,150 → 2,850–3,050 in the Supreme log, with the set page confirming a −300 (−9.52%) move versus the prior snapshot and stability tagged Underpaid For.
On the Chroma Beach Set value page, the tracked total reads about 2,850 with demand 5/10, last updated September 16, 2026. The set bundles Chroma Beachy and Chroma Sands; the homepage “falling” panel still lists both pieces with roughly −9% to −9.7% moves on September 16, matching the set-level crash rather than a one-knife glitch.
Trade read: If you still hold live-event Beach chroma as “seasonal premium,” September 16 is evidence that premium is fading without a new summer loot table. Mid-inventory traders should mark inventory to the new midpoint, avoid averaging down into demand-5 chroma with accelerating red rows, and rotate into names with verified demand-6 greens on the same batch — Raygun, Alien Set, or Chroma Blizzard — instead of pairing Beach pieces with stale demand-6 screenshots from August.
How Beach differs from Blizzard this week
Chroma Blizzard Set and Chroma Blizzard Gun printed another +250 on September 16 at demand 6/10, while base Blizzard Set only ticked +10. That split is the opposite of Beach: capital is parking in off-season winter chroma with rising demand scores, not in the 2026 summer box chroma line. Compare seasonal lanes on the MM2 Chroma values list before you swap Beach into “any chroma” upgrade offers.
Chroma Constellation at 31,000 — first −1K tick at demand 7
Chroma Constellation Gun has been one of the post-event winners, climbing toward 33,000 at demand 7/10 while base Constellation Gun lost demand 6 weeks ago and kept sliding. September 16 marks a tone shift: the chroma printed −1,000 to 31,000 in the Supreme batch even though demand stayed 7/10, and the base gun dropped another −100 to 3,000 at demand 5/10.
That is the same two-speed story traders saw with Raygun versus Chroma Raygun, but at a higher price bracket: chroma headline value can fall while demand looks elite, because list makers are catching up to real offers after weeks of grind-higher. If you use chroma Constellation as upgrade collateral, treat 31,000 as a new anchor and re-check the batch date — not the 33K meme offers still circulating in Discord trades.
For base Constellation pieces, the September 16 −100 row continues the post-demand-5 bleed. Pair set totals on the calculator with Celestial Set (also −150 today) rather than pricing Constellation knife/gun lines from memory.
Celestial Set −150 — Sun Set playbook step three
September 14 dropped Celestial Set from demand 6 → 5 without a huge value cut. September 16 delivered the follow-through traders label step three of the “Sun Set playbook”: demand already down, then a red value print — −150 to about 5,600 in the batch, with the Celestial Set page updated September 16, 2026 at demand 5/10.
What it means: Celestial is no longer competing with Raygun or Alien Set for easy demand-6 exits. Holders rotating out should prioritize trades into September 16 greens (Raygun +100, Alien Set +100, Chroma Blizzard +250) instead of waiting for demand 6 to return. If you bought Celestial on the September 10–13 climb, today’s −150 is a liquidity tax, not proof the cluster is “dead” — but it is proof the upgrade cluster is past its peak ease.
Raygun +100 at demand 6 — grind higher, not a surprise flip
Yesterday’s story was Raygun reclaiming demand 6/10. September 16 is about follow-through: Raygun added +100 to roughly 1,900–1,950 while staying at demand 6/10 in the Supreme log. The homepage “rising” panel still lists Raygun at about 1,900 (+100, +5.56%) on September 16.
On the Raygun value page, check the latest update stamp before you accept trades — demand 6 on a sub-2K Godly usually means easier swaps into other demand-6 classics, not automatic overpays. Use the MM2 Godly values list to stack Raygun with Darkshot, Darksword, Blossom, or Sakura when building a fair total toward chroma upgrades.
Chroma Traveler's Gun −5,000 again — mega-cap sync to 160K
The September 16 Supreme batch did not include a separate Chroma Traveler's Gun row, but the homepage and item “today” text logged another −5,000 move — about 165,000 → 160,000 (−3.03%) — with demand still listed at 8/10 and stability Underpaid For on the Chroma Traveler's Gun page.
Mega-cap chroma remains a split screen: Traveler's, Chroma Evergun, and Chroma Evergreen keep printing red in batches or syncs, while Chroma Blizzard and Chroma Raygun stay green on the homepage. Cross-list spreads are still wide on Traveler's (FAQ references cite separate MM2V and Supreme notes far above the 160K sync midpoint). Confirm which list and which date your trade partner uses before partial trades.
What traders should do today
- Mark Beach chroma to September 16. The −300 set print and ~−9% piece moves are the clearest post-summer unwind signal on today’s batch.
- Treat 31K as the new Chroma Constellation anchor. Demand 7 did not prevent a −1K tick — do not price upgrades off 33K screenshots.
- Expect Celestial red lines after demand drops. −150 today matches the Sun Set / Vampire playbook traders saw in early September.
- Separate batch rows from homepage sync. Traveler's −5K may not appear as a dated Supreme row even when the site movers panel updates.
- Run the calculator last. Compare totals on the MM2 trade calculator, then read demand and stability on each item page before accepting.
Murder Mystery 2 on September 16, 2026 is a rotation story: summer chroma finally breaks, constellation chroma cools at the top, Celestial prints red after its demand exit, and Raygun plus Chroma Blizzard keep absorbing capital on the same Supreme tape. That is community pricing — not an official update — but for traders, the September 16 batch is the headline until Nikilis ships the next patch.
