The official Roblox universe metadata previously showed the experience title as [UPD] +1 Muscle Evolution. The August 1 check shows the title as [W2] +1 Muscle Evolution and records an update on July 31, 2026 at 22:54:16 UTC. No selected official source explained the prior UPD label as a patch-note list, event reward or code drop.
Roblox public metadata no longer shows [UPD] in the title and now shows [W2] while listing the same core loop of Damage, punching bags, enemies, stages, Wins, Evolutions and areas. Until a creator-owned source explains the prior label, this page checks for codes, event terms and patch notes without inventing them.
Roblox public metadata is the source for the current title, updated timestamp, creator group, visits, favorites and current core description.
No public creator-owned patch notes, reward table, code string, pet roster, Evolution list or event mechanics were found in this run.
Old Muscle Evolution, Muscle Legends, +1 Magic Evolution and +1 Muscle to Arm Wrestle code claims do not belong to this universe unless a current source binds them here.
