Fighting in a vacuum is perhaps the most challenging environment for PCs to contend with. While breathing in a vacuum is a simple matter thanks to the basic environmental protections granted by armor, movement in zero gravity is tricky. This doesn't mean fighting in a vacuum is a highlevel threat! On the contrary, zero-gravity environments are commonly encountered all throughout a character's adventuring career.
To run efficient encounters in a vacuum, ensure you and your players know how the untethered condition and Push Off action function. Many characters will develop strategies to mitigate the untethered condition or its penalties, whether through ancestry feats, magic spells like personal gravity, or technological items like magboots. Even simple cables used as a tether can be useful tools to PCs fighting in a vacuum!
Ensure the environments you describe have plenty of material around for PCs to Push Off of, cling to, use as cover, and fling at their attackers. Remember that the threat of being pushed out a starship's airlock or falling off a ruined structure floating in the Drift can bring an effective narrative tension to an encounter, even if the PCs manage to avoid being tossed into the vacuum!
