MM2 Day 28 Trading Map: Alien Set Keeps Demand 6 as Constellation and Celestial Hold at Five

Last updated: September 20, 2026

Murder Mystery 2’s value board on post–Summer Event Day 28 is a rotation story, not a headline patch. Supreme’s last full batch on MM2 Calculator’s value changes log remains dated September 17, 2026 (19 rows), with no September 18, 19, or 20 batch table yet — a triple digest after the September 18, 2026 homepage sync. The clearest signal in that September 17 tape is generational: Alien Set reclaimed demand 6/10 at roughly 3,750–3,800 (+100), while Constellation Gun (~2,900, −100) and Celestial Set (~5,400–5,450, −200) stay at demand 5 after earlier downgrades. The demand-6 lane that still prints green on the homepage — Raygun (~1,950, +50), Darkshot (~1,800, +25), Darksword (~1,775, +25), and winter-prep Chroma Blizzard (~5,250, +250) — is where most liquid offers still clear. Run every counter-offer through the free MM2 trade calculator before you swap 2024 rotation names for 2025 set pieces.

Compare both sides in the MM2 trade calculator before swapping a demand-5 2024 name for a demand-6 2025 set piece.

September 20 at a glance — triple digest, Alien IN vs 2024 OUT

Summer Event 2026 closed on August 23, 2026. Supreme has repriced on a rough one- to two-day cadence since then; September 17 was the most recent multi-row batch. September 18 brought a homepage refresh (still reflected on item pages such as Raygun and Darkshot with “last updated September 18, 2026”), but the changes log has not added dated batch rows for the 18th–20th window at the time of this draft.

No verified Nikilis patch note or Roblox game-page changelog tying September 20 to new tradeable Godlies was found in first-party channels checked for this draft. Numbers below are community value-list data on MM2 Calculator — not official Roblox prices.

Why Alien Set is absorbing capital while Constellation stalls

The September 17 batch did not invent the Alien story — it confirmed a handoff traders have watched since mid-September. On September 14, Supreme logged Alien Set upgrading from demand 5 → 6 alongside a Raygun +50 demand upgrade to 6. Three days later, the set printed another +100 value line while Constellation Gun took a second −100 cut at demand 5, echoing the “Sun Set playbook” that already pushed Vampire's Gun, Evergreen, and Vampire's Set off the demand-6 shelf in early September.

Trade read for mid-tier inventories: Constellation Gun near 2,900 and Celestial Set near 5,400 are still expensive Godlies — but demand 5 and “Receding” stability on the godly list mean upgrades into them need extra overpay, while exits into Alien Set or the Dark Set shelf often meet faster counters. The Raygun MM2 value page notes Raygun pairs with Alienbeam as the Alien Set; with Raygun itself at demand 6 and “Doing Well,” completing or upgrading that 2025 pair is structurally easier than holding a lone Constellation piece waiting for demand 6 to return.

Chroma contrast: Base Constellation’s slide sits opposite a firmer Chroma Constellation Gun (~31,000, demand 7 on the chroma list) — a familiar MM2 split where the chroma cap and base gun do not move in lockstep. On September 20, treat chroma and base as separate tickets; do not assume a green chroma line saves a red base line.

The demand-6 shelf — Raygun, Dark Set, and Blizzard as liquidity anchors

During digest windows, traders still need “parking” items — Godlies that clear near list without mega-cap risk. That lane stayed intact through September 18 homepage movers and unchanged item-page stamps on September 20.

Raygun stack. Base Raygun at ~1,950 with demand 6/10 and stability Doing Well has printed repeated +50 rows since mid-September. Chroma Raygun at ~14,000 (+250 on the homepage) gives chroma traders a parallel ladder — useful when sellers ask for overpay “because Hunt players are online.”

Dark Set bridge. Darkshot and Darksword near 1,775–1,800 with demand 6/10 remain the classic shelf for offers in the 1,750–1,850 band. They do not compete directly with Alien Set numerically, but they compete for the same counter-party attention when Constellation sellers need a downgrade target.

Chroma Blizzard winter prep. Chroma Blizzard Gun near 5,250 with demand 6/10 continues a mid-September green streak (including +250 rows on September 14 and September 16). For players rotating out of summer chroma, Blizzard remains the seasonal “IN” name on the MM2 chroma values board while Chroma Evergun and Chroma Traveler's Gun stay on the red side of the homepage.

High-end chroma pressure — do not use Ever pieces to fund Alien upgrades blindly

The September 17 batch extended the Chroma Ever cluster selloff: Chroma Evergun (~58,000, −2,000), M2 Chroma Ever Set (~99,000, −2,000), and homepage Chroma Traveler's Gun (~155,000, −5,000) still lead “Falling” movers. Several carry Underpaid For tags on the chroma list — a warning that list value and accepted offers can diverge when sellers rush exits.

Practical rule: If you are upgrading into Alien Set or Raygun, prefer funding from another demand-6 mid-tier or a controlled partial downgrade — not a panic sell of Ever chroma into a digest-week bid gap. Use the MM2 values list to compare demand and stability on both sides, not just totals.

Hunt week footnote — more players, same September 17 tape

The Hunt: Roblox 20 (community guides widely report September 17–28, 2026) keeps Murder Mystery 2 lobbies busy with the 50-coin objective and free Knife-Dodger's Bighead avatar accessory. That traffic is real, but it is not the same as a Supreme reprice: digest days can still see more lowball offers from players who confuse Hunt coins with trade value. On September 20, anchor negotiations to the last dated Supreme rows — Alien IN, Constellation OUT — not to weekend lobby volume alone.

What to watch before the next batch

• Batch return signal: A new date header on the value changes log above September 17 — watch for whether Constellation gets a third cut or Alien Set holds demand 6 without a downgrade follow-through.
• Sync-only moves: Homepage-only rows (for example high-end chroma pulls) can appear without a full batch table — label them as sync in your notes.
• Offer hygiene: Demand 5 on Celestial and Constellation means “fair by value” trades can still feel lose on time-to-fill; prefer demand-6 targets when you need speed.
• Hunt deadline: Guides cite the event closing September 28, 2026 — liquidity may spike again near the end; plan trades before the final weekend if you dislike volatile lobbies.

Murder Mystery 2 values are community estimates. Demand, stability, and batch timing decide real trades more than any single number — use the calculator, then confirm the latest row date on the changes log before you accept.

Quick FAQ

Is Alien Set the safest upgrade lane on Day 28?

It is the clearest demand-6 handoff in the source's dated rotation map, with Alien Set around 3,750–3,800 after a +100 line. That is a relative signal, not a guarantee of faster trades or future gains.

Why are Constellation Gun and Celestial Set marked OUT?

Both remain at demand 5 after follow-through cuts: Constellation Gun is around 2,900 after −100, and Celestial Set is around 5,400–5,450 after −200. Compare current demand and stability rather than value totals alone.

Was there a September 20 Supreme batch?

No dated September 20 batch was verified for this draft. The latest full rows remain September 17, while the September 18 homepage snapshot supplies separate sync and item-page context.
