Xbox Wire on September 11, 2026 detailed METAL SLUG Ultimate Collection, SNK’s 30th-anniversary ten-title set spanning arcade, home, and handheld Metal Slug games plus a legendary never-officially-released location-test build. Wishlist is live on Xbox; modern quality-of-life callouts include rewind, quick save, infinite ammo, and Combat School modes.
Platform framing in first-party materials checked for this filing covers PS5, Xbox Series, Switch, Switch 2, and Steam. The calendar lock is a 2027 year window only — no street day and no invented price. This desk will not upgrade the year window into a fake month, invent a day-and-date, or confuse the anniversary with a 35th.
Why it matters for a US Xbox desk: a clean first-party Wire drop with a genuine unreleased build hook and multiplat wishlist presence, without forcing a date that SNK has not published. The location-test inclusion is the collectible headline for longtime run-and-gun fans; the rest of the set is the 30th-anniversary package framing, not a new original Metal Slug campaign announce.
Readers should wishlist where available and treat 2027 as the only locked calendar language until SNK or a platform partner publishes a month or day. Cross-platform presence across PlayStation, Nintendo hardware, and Steam means this is not an Xbox exclusive SKU story — Xbox Wire is simply the clearest first-party English write-up on the day.

What we are not saying: no invented street day or price, no 35th-anniversary claim, and no claim the location-test build was previously sold at retail.
When a store page adds a month, edition SKUs, or a firm price, that will be a separate update. For now the accurate line is a ten-title 30th-anniversary Metal Slug Ultimate Collection, wishlist live, multiplat including Xbox, and a 2027-only window.
