Suffocating or unable to sprint with two helmets equipped
Tracked since 15 Sept 2026 · Last researched 15 Sept 2026
Problem
If your heart rate keeps climbing, your character starts suffocating, or you cannot walk fast or sprint even though a helmet is on, check whether a second helmet is attached at your hip.
RSI says this happens when one helmet is in the hip attachment slot and another is in the helmet slot. The issue is still listed for Alpha 4.10.x.

Remove the second equipped helmet
Leave only one helmet equipped. RSI lists removal of the second helmet as the current fix for this exact two-helmet problem. It is the best first step, but there is no public Alpha 4.10.x player success rate and older hidden-helmet cases did not always clear.
RSI identifies the extra hip-slot helmet as the trigger and says removing the second helmet fixes the breathing, heart-rate, and movement symptoms. An older player report confirms this worked, while other older reports describe a hidden helmet that stayed stuck.
What to do
- Remove the second equipped helmet so only one helmet remains on your character.
Use this when one helmet is attached at your hip and another occupies the helmet slot.
Boundaries and evidence
RSI does not name the exact affected 4.10.x hotfix, how often the issue occurs, or how often removing the extra helmet works.
No public Alpha 4.10.x player test was found for this exact problem. Older reports are mixed, especially when the hip-slot helmet is invisible or cannot be removed with Alt+H.
The exact Issue Council history and fix target are not publicly inspectable.
