can i revive my friend if theyre knocked out

Yes, approach your unconscious teammate and use a First Aid Kit on them to wake them up and restore some health.

does regular armor still work the same way

No, armor now only protects the specific body part it covers (helmet protects head, chestplate protects torso, etc.), so you need to wear a full set for complete protection.

what do i do about bleeding and fractures

Treat bleeding with appropriate medical items before it drains your health, and use healing supplies to recover from fractures—left untreated, these status effects will kill you over time.

why is my screen blurry and red

This happens when you're in pain or losing blood; the visual effects warn you that you need to heal immediately.

can i turn off the limb system if its too hard

Yes, you can disable status effects like bleeding and fractures in the configuration, or turn on Simple Armor Calculation to revert to normal armor rules.

do mobs attack me when im knocked out on the ground

No, hostile mobs will ignore you while you're unconscious, giving teammates a chance to revive you safely.

Frequently asked questions

How do I check which body parts are injured?

Press the O key to open your Character screen, where you'll see health bars for each limb (head, torso, arms, and legs) along with any active status effects like bleeding or fractures.

What happens if my head or torso reaches 0 health?

You die instantly, even if your other limbs are at full health—these vital parts cannot be healed and losing them is fatal.

How do I fix a broken limb?

Craft an

Emergency Surgery Kit, then hold right-click on the broken limb for about 15 seconds to fully repair it.

Why am I moving so slow and hungry all the time?

If your legs are damaged, you'll move slower, and if your stomach is damaged, you'll lose hunger faster—you need to heal these specific limbs to restore normal function.
