Enemy
Slime
Updated:
An environmental hazard — a viscous puddle on the floor that needs to be cleaned up rather than fought.
Overview
Slime is the environmental-hazard enemy class — a stationary viscous puddle that materialises on a hospital floor and needs to be cleared with the right tool. It doesn't pursue, attack, or have any animation cues; it just exists in your path and exacts a cost (sanity drain plus movement slowdown) on anyone who walks through it untreated.
The encounter reads as a chore rather than a combat threat. Spot it, mop it, move on. The reason Slime gets enemy-class treatment rather than living in a generic hazards list is that it can block critical movement paths — if a slime patch is between you and an emergency room during an active event, the cleanup becomes the immediate priority.

Key Mechanics
Static environmental hazard. Doesn't pursue, but blocks or hinders movement through the area until cleared.Pros & Cons
Pros
- ✓ Static — no chase, no animation triggers, no surprise attacks
- ✓ Has a dedicated cleanup tool (Mop) that resolves it cleanly
- ✓ Visual cue (glistening puddle) is unambiguous and easy to spot
Cons
- ✗ Walking through it drains sanity and slows movement, so ignoring it has compounding cost
- ✗ Can block critical movement paths during emergency events, forcing reroute or cleanup-first triage

How to Handle
When you spot a glistening puddle on the floor, grab a Mop from supplies and clear it. The mop interaction removes the patch entirely — no follow-up cleanup or item swap required. This is the only weapon class that works; Gun, Taser, and Fire Extinguisher do nothing against Slime.
If you don't have a Mop on hand and you're moving through a corridor with a slime patch, route around it. Walking through untreated drains sanity and slows your sprint, which compounds quickly during multi-room emergency runs.
During active emergency events, evaluate cleanup priority against the event timer. If a slime patch is between you and an emergency room and detouring would burn more time than mopping, mop first. If the detour is fast, leave the slime for post-event cleanup. The patch doesn't grow or change while you ignore it.
Patch History
No major updates documented for Slime. Mop cleanup behaviour has been stable since launch.

Frequently Asked Questions
- Use the Mop on the puddle. No other weapon class works — Gun, Taser, and Fire Extinguisher have no effect.
- Sanity drains and your movement speed drops. The effects don't persist after you leave the puddle, but the cost compounds if you cross it repeatedly.
- No. It's a static environmental hazard — it stays where it spawns and doesn't change shape or position until cleared.
- On hospital floors throughout the facility. Specific room weightings are not documented in the current source set.

An environmental chore, not a fight
Slime is documented as a viscous puddle on the floor — somewhere between an enemy and a hazard. The encounter is essentially a cleanup task: apply the Mop to the puddle, wait for it to clear. No combat, no timer, no decisions.
Per Destructoid: "clear by holding E" with the appropriate tool. The Mop is the named cleanup item.
What walking through it costs
If you ignore the Slime and walk through it instead of cleaning it, two consequences are documented:
- Sanity drain on contact.
- Movement slowdown through the affected area.
Neither is fatal on its own, but during a busy shift (especially Shift 4+ ambulance waves where transit speed matters), a Slime puddle between rooms can compound with other time pressures. The clean-on-sight discipline is worth the few seconds.
When the Mop isn't in reach
If you're caught without a Mop and a Slime is blocking a path, route around it rather than through. The sanity drain isn't worth pushing through when an alternate path exists. Pick up the Mop on the next cabinet pass and come back.
Source-coverage note
Slime gets less detailed documentation than the marquee enemies (Bed Monster, Skinwalker, Mass of Eyes). The cleanup-with-Mop mechanic is widely confirmed; specifics like sanity-drain rate per second are not. Marked confidence: verified on the core mechanic, with the understanding that quantitative details may vary by patch.
