Paramedic

Weakest

Cost

250 Animal Coins

Perk

Start with Run Fast Cola (6-9 uses)

A niche pick focused on movement speed. The Run Fast Cola helps you zip around the hospital, but the lack of meaningful utility makes it hard to recommend over other options.

Niche

Level	Effect
1	Start with Run Fast Cola (6 uses)
2	Start with Run Fast Cola (9 uses)
3	Start with Run Fast Cola (9 uses), regenerate 1 use each round

Secretary

Sanity Classes

Cost

120 Animal Coins

Perk

Recover sanity when checking in patients

A budget-friendly sanity management class. Each patient you check in at the front desk restores a small amount of sanity. Great for learning the sanity mechanics without pressure.

Beginner

Level	Effect
1	Recover 1 sanity per check-in
2	Recover 1 sanity per check-in, +5 bonus sanity
3	Recover 1 sanity per check-in, +10 bonus sanity

Psychologist

Sanity Classes

Cost

500 Animal Coins

Perk

Double all sanity effects, chance to ignore sanity loss

A high-risk, high-reward class for expert players. All sanity gains and losses are doubled. At higher levels, a chance to ignore sanity loss provides a safety net. One mistake can still cost you the run.

Expert

Level	Effect
1	All sanity effects doubled (positive and negative)
2	All sanity effects doubled, 7.5% chance to ignore sanity loss
3	All sanity effects doubled, 15% chance to ignore sanity loss

Doctor

Sanity Classes

Cost

900 Animal Coins

Perk

Recover sanity when healing patients

A solid mid-tier class that pays for itself through sanity recovery. The bonus sanity cap at Level 2 makes it easier to survive longer shifts. A stepping stone to Surgeon.

BeginnerSolo

Level	Effect
1	Recover 1 sanity per patient healed
2	Recover 1 sanity per patient healed, +15 bonus sanity
3	Recover 1 sanity per patient healed, +20 bonus sanity

Security

Which Class Should You Pick?

F2P (Free-to-Play)

Start with Nurse (20 Animal Coins). It is cheap and the extra inventory helps enormously. Save up for Surgeon (2,500 Animal Coins), the best F2P class in the game. If you need sanity support, grab Doctor (900 Animal Coins) as a mid-tier stepping stone.

Robux

If you are willing to spend Robux, Head Nurse (80 Robux) provides incredible team utility with its massive inventory. Secret Agent (320 Robux) is the best solo class, letting you handle anomalies with ease right from shift 1.

Frequently Asked Questions

Which class should I buy first?

Get Nurse (10 Animal Coins) first for the inventory upgrade, then save for Surgeon (2,500 Animal Coins). It's the best F2P path.

Are Robux classes worth it?

Head Nurse (80 Robux) is excellent for team play. Secret Agent (320 Robux) was buffed in Harlow's Update — now starts with a Scanner at Level 1. Both are quality-of-life upgrades.

Did Harlow's Update change the class meta?

Yes. Secret Agent and Security were both reworked. Secret Agent now starts with a Scanner at Level 1, making it even stronger. Security gains a Deployable Camera at Level 2. Any tier list from before July 10, 2026 is outdated.

Can I change classes mid-game?

You can change classes between shifts in the lobby. You cannot switch during an active shift.
