How to Sleep and Remove Trauma
State of Decay 2 inflicts ailments on player characters over time like fatigue and trauma. Fatigue happens if your character is out and about too long. The longer they're out running and killing zombies, the more fatigued they become. This limits the character's stamina bar.
Trauma happens after a character takes a big hit from a zombie or other enemy. This has to be cured with rare medical items or the Infirmary facility. Learn more about this in the section below.
How to Sleep/Fix Fatigue
After playing a bit of State of Decay 2, your survivor will naturally get sleepy. State of Decay 2 requires you to play each character in your community this way.
In order to sleep, go back to your base and swap characters. After a few in-game hours, the character recovers from fatigue. You'll receive a notification when this happens.
You can drink things like coffee and energy drink to push off fatigue, but we have yet to find anything that completely takes it away. Craft coffee and energy drinks at your base's kitchen if you have one.
If you don't have enough beds in your community for every person the characters recover slower from fatigue.
How to Cure Trauma
Trauma prevents a character from being able to get back to full health, and if the trauma is bad enough, it can also limit their stamina. Trauma can also impact their mood. You can get a detailed report of the exact trauma a character suffers from in the Community tab.
You can cure trauma with items like first aid kit or with an action at your base's infirmary. If you don't have an infirmary because you don't have a character who has some sort of medical skill, get on that right away. You can randomly find medical textbooks that teach the medical skill in infirmaries, ambulances, and other medical structures.
If you have the standard infirmary at your base, you can heal your active character at any time so long as you have at least 3 medicine in storage. There's also an option to heal the entire community's trauma if you have enough resources and meet the skill requirements. Even better, if you have an Infirmary level 2 or better, your characters will recover health AND trauma over time so long as they're at the base.
