Checked October 2, 2026W3 appeared in the official experience title on September 26, 2026; the marker has since advanced to [WORLD 4]. This page keeps the W3 record exactly as verified - and refuses to invent speed gates, maps or rewards that no public source documented.
Update watchSource: official Roblox metadata
Quick answerThere was a [W3] wave: the official Roblox experience was named [W3] +1 Mog Evolution (verified September 27, 2026 after the September 26 update, re-checked October 2, 2026). The title later carried [WORLD 4] (checked October 11, 2026) and then a generic [UPDATE] tag (October 17-25, 2026, checked October 18) - the October 25, 2026 bump removed the tag entirely (checked October 26, 2026) - see the World 4 status page and the updates log. What W3 contained, how it unlocked, and what it rewarded were not published anywhere official - and community claims about them stay labeled as reports on this page.
