What the 9th anniversary post lists
The 2026-09-07 changelog says the 9th anniversary brought a new Facility_0 by deadlybones28 on the same layout with finer models, circus bundles and crates, lobby decorations, a collector UI, private-server map picking, and percent readouts for computers, exits, and captures. It also says private servers can play old maps and old versions, back to the 2017 Facility_0.
Beast changes in that post: Runner no longer has hit-slowdown, and Stalker’s passive heartbeat radius is 5 studs smaller. A merchandise note describes a Beast chibi plush keychain and an in-game Dark Bone Crusher Plush hammer plus Default Plush gem for orders.
The 8th, with a gap
Fandom’s 8th Anniversary Hammer is legendary, tagged Anniversary, paired with the 8th Anniversary Gemstone, from the 8th Anniversary Bundle at 1,500 credits, and listed as limited. I do not have the 8th’s opening and closing dates from that page. I will not borrow the 9th’s length and pretend it matches.
