How do you avoid brain damage in Casualties Unknown?

1. Take sound cannons seriously. You get about five seconds. Dig or duck behind a solid wall.
2. Learn the coil. It will not kill you, but you can pass out for long enough for something else to.
3. Wear head protection. Crafted or found helmets give you a chance against falls, and head armor needs a carcass from a shade crawler. confirmed
4. Respect blood pressure. See heart and stroke for what to do when you hit a hypertensive crisis.
5. Do not fight underwater near anything that explodes.

What should you do right after being hit?

Stop moving, open the health panel and check the brain bar, then look for a stroke marker. If you are also bleeding or dislocated, handle bleeding first, because you can survive reduced brain health for longer than a serious bleed.

Do not panic-drink. Spending your only Braingrow on a small amount of damage leaves you nothing for a stroke. Players often keep it until there is an active stroke or a serious loss.

Why does my character’s speech look strange?

That is an intended effect of brain damage and strokes. Your character’s words appear with repeated characters and pauses, and the same applies to some other severe conditions. If it starts suddenly and your bar is dropping, you may be having a stroke, so check for that first and use the stroke treatment if you can.

The 6.0 notes also say that being in a bad state changes moodles and dialogue. Learning to read these clues is especially useful if you play unchipped, when numbers are hidden from you.
