Casualties: Unknown Beginner Guide for the 1.0 Release

Why the first hour feels unfair

The official store description calls Casualties: Unknown an unforgiving cave-exploration survival simulator, and one beginner guide puts the problem plainly: the game does not explain the mechanics that kill you. It gives you a light, a cave and a body that can bleed, break and panic. That is why the opening hour is mostly about learning systems, not about pushing depth.

Start with the built-in courses

Both beginner guides checked here point to the in-game training courses before a serious run. One describes them as covering movement, items, first aid basics, containers, crafting and sleep, with more advanced First Aid and Crafting courses unlocking after reaching later layers. Doing them first is cheaper than discovering the same lessons with a tourniquet. If you prefer a blind first run, play the tutorial, lose one character and then come back to these pages.

The first layer

The Gravel Lands are described as the safest layer in the game, which is not the same as safe. A widely viewed tips recording frames getting past the first few layers as the first real milestone. Treat the opening area as a place to gather light sources, containers and dressing materials rather than as a race to descend. The survival basics page covers the light and water tasks that usually come up here.

Craft without juggling everything

Crafting can consume ingredients lying on the ground nearby, so you do not need to hold every item in a hand slot. The same tips recording notes that loose materials and tools on your person are used up before bagged ones, which is convenient until a recipe eats the only tool you wanted to keep. Marking gear as favourited keeps recipes from using it up. That matters especially for the rope and tool recipes, where a single rope is easy to lose to an unrelated craft.

Before you sleep

Sleeping with open wounds is a risk, and the store description says blood loss must be stabilised before losing consciousness. Deal with active bleeding first, then rest. The internal bleeding page explains how the health panel shows blood volume falling, and injuries and revival covers infection and shrapnel.

Where the evidence stops

These guides paraphrase training courses and patch notes written for the demo 7.0.1 build, and at least one says its mechanics had not been checked against the released game. Treat exact control keys, unlock layers and numerical thresholds as build-dependent. No first-hand gameplay testing is claimed here.
