How many players can play Animal Hospital together?
Servers hold up to 30 players per the official Roblox record, but a shift squad of two to four covers the documented roles cleanly — reception, treatment, mobility, and defense. Beyond four, extra players duplicate coverage rather than add it.
What is the best two-player split?
Desk versus rooms. One player owns the four-layer check and the Sanity machines; the other owns treatments, the extinguisher, and event running. It maps naturally onto Secretary-or-Psychologist plus Doctor-or-Paramedic.
Who should handle the Ambulance Event?
The mobility role: a Paramedic's speed kit plus anyone carrying the extinguisher. The event guide's preparation list (empty rooms, reachable extinguisher) is a squad checklist, not a solo one.
Which class defends against entities?
Security (Deployable Camera at level 2, regenerating X-Taser at level 3) and Secret Agent (Gun plus Scanner starter) are the documented defense kit; the Firefighter added July 25 covers fire and slime cleanup with its self-recharging extinguisher.
Do all squad members need different classes?
No documented rule requires it, but duplicated classes duplicate the same weakness. Cover roles first — the roster table's eleven documented classes are built to interlock, not to stack.
What squad change fixes dying runs fastest?
Add or assign a Sanity keeper. Low-Sanity mistakes cascade — photo grabs, wild tases — and a player who owns the machines and the Chocolate Bar supply removes the documented losses faster than any damage role.
