Casualties Unknown Beginner's Guide
Most first runs end for boring reasons: no light, no water, an untreated wound, or a fight the player did not need. This guide puts those four problems in order.
Quick answer
- Secure light first, then water, then a way to treat bleeding. Loot comes after those three.
- Open the wound view after every fight, even when the screen looks calm.
- Do not sprint into a new area with an untreated wound or an empty light source.
- Leave the run while you still have supplies; a survived run with little loot beats a death with a full bag.
What to do in your first ten minutes
Treat the opening as a setup phase, not a looting phase. You are trying to leave the first area with four things: a working light, a drink, a bandage or equivalent, and a mental note of the route back.
Move slowly enough that you can hear the environment. The game punishes players who sprint through doorways because sound and sight lines matter more than speed. If you hear something you cannot identify, stop and look before you commit to a room.
- Light: without it, you cannot read rooms or spot hazards reliably.
- Water: thirst is a slow problem that becomes a fast problem.
- Bleeding control: one untreated wound changes every later decision.
- An exit plan: know which direction you came from before you go deeper.
If you find a container or a tool before you find water, that is fine, but do not let a full bag talk you into staying longer than your supplies allow.
How to read the HUD without panicking
The interface is trying to tell you two different things: what is wrong right now, and what will become wrong soon. New players usually read only the first one.
Check three layers in this order:
- Immediate danger: bleeding, a broken limb, a hazard you are standing in.
- Direction of travel: are the status cues getting better or worse since the last room?
- Resources: light, water, medical supplies and weight.
If you cannot answer the first question in one glance, stop moving. The game does not require you to interpret a wall of icons while running. Stand still, read the cues, then act.
What to loot first
Loot in the order that keeps the run alive, not the order that makes the bag look impressive.
| Priority | What to look for | Why it comes first |
|---|---|---|
| 1 | Light source and batteries | Without light you cannot evaluate anything else safely. |
| 2 | Water and a container | Thirst compounds while you explore. |
| 3 | Bandages or bleeding control | A wound you cannot treat limits your route. |
| 4 | Weapons you can actually use | A heavy weapon you cannot aim is worse than a light one you can. |
| 5 | Trade goods and curiosities | Value matters only after survival is handled. |
Weight is a decision, not a score. Carrying three items you will never use costs you stamina and attention on every later room. If a pickup does not answer one of the four first-run problems, ask why it is in your bag.
Check wounds after every fight
The most common beginner death is not a boss or a trap. It is a small wound that was ignored because the screen looked normal. Open the wound view after every encounter, including encounters you think you won cleanly.
Ask three questions:
- Is anything bleeding, and is it getting worse?
- Do I have the supply to treat it now, or do I need to leave?
- If I treat it now, what do I have left for the trip back?
If the answer to the second question is "no", the run is over. Walking deeper with an untreated wound is borrowing time at a bad interest rate.
When to leave a run
Leave when any one of these is true:
- You have no reliable light.
- You are out of water and have no route to more.
- You have a wound you cannot treat.
- You are making decisions based on what you hope is in the next room rather than what you have now.
Experienced players extract earlier than beginners expect. The goal of a first run is not to see everything. It is to learn the loop, keep the character, and come back with a better plan. A small successful run teaches more than a long run that ends in a death screen.
Five mistakes that end runs early
- Sprinting everywhere. You arrive tired, loud and unable to react.
- Ignoring the wound view. The damage is often already done when the screen gets loud.
- Fighting every contact. Most encounters are cheaper to avoid than to win.
- Hoarding weight. A full bag slows the decisions that keep you alive.
- Treating the first run as a tour. The first run is a lesson about the loop, not a completion attempt.
Fix these five and your survival rate will improve before you learn a single advanced trick.

0 / 6 doneFrequently asked questions
What should I do first in Casualties Unknown?
Find light, water and a way to treat bleeding before you loot for value. Those three resources decide whether you can keep playing the run.
How long should a beginner run last?
Long enough to learn one route and short enough that you still have supplies when you leave. If you are guessing about your next room, you have stayed too long.
Should I fight every enemy I see?
No. Avoidance is usually cheaper. Fight when the encounter blocks the route you need or when you can end it quickly and safely.
Why do I keep dying after a fight?
Check the wound view immediately after combat. A small untreated wound often turns into the reason the next room kills you.
Is Scav Prototype the same game as Casualties Unknown?
Yes for search intent: players still type Scav Prototype, while the current public title is Casualties Unknown. This site covers both names.
Does this guide work for the demo?
The survival loop described here applies to the current playable build. Exact item names and balance can change between versions, so verify anything numeric in-game.
