Begin with Basic Training, then prioritize a container and dressings. Casualties: Unknown rewards understanding the interface before exploring deeper; the developer’s course explicitly teaches those two supply priorities.
Your first useful actions
- Right-click yourself to open the inventory. Right-click and drag a ground item onto yourself and then into a slot to pick it up. Hold Control to reveal item labels.
- Keep a usable tool in your main hand. Left-click swings it; Q swaps the items in your hands.
- Open crafting with C. Make storage before collecting more supplies than your slots can hold, then prepare dressings.
- Open the health panel with R after an injury. Hover the affected limb before choosing a treatment; skin and muscle are separate values.
Do not rush past the warning
A wound can keep bleeding after you stop fighting. The tutorial shows dressing dragged onto the injured limb, then wrapped using the left mouse button. Infection needs its own treatment; a dressing is not a universal repair.
The game also separates stamina from longer-term energy. Digging and jumping can exhaust you, so avoid turning every obstacle into a lengthy excavation.
Before you stop playing
Save at a layer transition using Save and exit. Quitting in the middle of a layer erases progress according to the current menu text. Read saving rules before closing a valuable run, and return to First Aid once the course unlocks.
