Full Update & Version Timeline
New Content + X2 COINS
X2 COINS + New Content - dated 2026-09-19; full patch notes on the Updates page.
Second Floor Expansion
The biggest September drop: a whole new hospital floor with the Sewers area, the DNA-powered Laboratory, a fresh batch of potion recipes, and four event skins.
Even More Lore! Update
A story-first patch that opened one more location for lore hunters, shipped the quality-of-life fixes players had asked for, and added new skins for the Doctor, Surgeon and Paramedic.
Dr. Harlow Event & Rain Shift Update
A Dr. Harlow event with hidden interactions plus the Rain Shift weather mode, extra Liz and visitor lines, Fast Start, reconnect support, four staff skins and a weekly leaderboard.
The Hazmat Team Arrives
The containment-breach event that introduced Sam and the Journal Collection System, added Slimebert and the slime shift, and brought the Firefighter class into the game.
Small Redesign Update
A cosmetic pass over the class models: softer fur and thinner antlers for the Surgeon, a nose detail for the Secretary, angled Paramedic ears, and a recoloured bandage sprite.
Harlow's Favorite Update
One of the year's largest content drops, adding the Liz NPC, a Dr. Harlow rework, three new items, reworks for Security and Secret Agent, and the Stalker's disguise mechanic.
Ghost Spawn Rule (Mini Patch)
A targeted fix rather than a feature: the Ghost now appears only after a patient has died mid-shift instead of spawning as a random encounter.
Class Update Pt.2 + More
The follow-up to the class overhaul, delivering the Skins tab in the class shop, controller support, and extra check-in anomaly tells.
Class Update Pt.1
The class overhaul proper: every class gained three upgrade tiers, shop cards began showing starting cash, in-game class models and a rebuilt perks UI arrived, and Secret Agent was moved to Robux-only.
Ambulance Update
Introduced the Ambulance emergency event, a high-pressure patient-delivery scenario that can trigger from Shift 4 onward.
New Upgrades
The earliest dated follow-up to launch: balance changes plus an upgrades pass aimed at making a run faster paced, the direction every later update built on.
Animal Hospital Official Launch
Day one on Roblox: five shifts, six classes, and the core anomaly-detection loop that everything since has been built on.
