Characters

A city this empty does not have many people left in it. The ones who are still moving matter more for it.

Who you play

Small, fast, and outnumbered.

Playable

The rat

A young sewer rat that survived the outbreak by being underground when it happened. Agile, curious, intelligent and resourceful — with no advantage over anything hunting it except size, speed and a very good nose. Its name has not been settled yet.

What is waiting

The things in the way.

Final boss

The Alpha Infected

The first creature the virus ever touched, and the reason it spread the way it did. It has not left the laboratory. It is between you and the antidote.

Zone 1 boss

The Nest Mother

What the sewers built while the city was busy dying. The first thing down there that cannot simply be avoided.

Who is left

Not quite alone.

Mentor

The Elder Rat

Knows the tunnels, remembers what the city was like before, and teaches you what the game will not stop to explain.

Story

Scientist recordings

A voice left behind on the facility’s systems. The closest thing to an account of what actually happened, delivered by somebody who did not get out.

World

Survivors and drones

Animals that have not turned, and laboratory drones still following instructions nobody is left to countermand.

Abilities

Everything the rat can actually do.

Sniff

Reads what passed through a space before you did — where an enemy went, where food is, which pipe is worth crawling into.

Climb

Pipework, wire, brick. Most of the route up is climbable if you can find the first hold.

Crawl

Into gaps nothing chasing you can follow through.

Swim

Flooded chambers are routes, not walls — though not everything in the water is dead.

Sprint

Fast, and expensive. Stamina is a real resource and running out of it in the open is how runs end.

Double jump

Unlocked later, and it reopens the map behind you — earlier zones hold routes you could not reach the first time.

Attack

A last resort. You are small and there are more of them.

Craft

Turns scavenged junk into the things that hold the infection back.

What you manage

Three meters, always running.

Health

Spent by contact with the infected and by hazards. Restored by food you have to go looking for.

Stamina

Spent by sprinting, climbing and swimming. Refills when you stop — which is not always an option.

Infection

Rises near the infected and does not fall on its own. Managing it is what crafting is for.

Experience

Earned by surviving, exploring and solving. XP is half of what opens the next zone — the other half is an object you have to go and find.
