When exploring the world of Starfield, you’re likely to come across various systems that take a bit of getting used to. Take the O2 system, for example, which acts as a form of sprint duration in the game that can lead to your death if you aren’t careful. One such mechanic is carried over from previous Bethesda titles but is confusing due to its changes since. Here’s how Mass works in Starfield.

What is Mass in Starfield?

Mass is the amount of weight that you can carry in Starfield. Each item that you’re holding onto is given a Mass value you can see when hovering over the item. Weapons and armor will always take up more mass, while items like Ammo will take up zero Mass due to how much you’ll need when exploring. This value is affected mainly by both stats on your armor and by the amount of points you have in the Weight Lifting skill under the Physical skill tree. The more points you have invested, the more that you can carry.

This normally won’t have an effect on you until you become Overencumbered (when your Mass exceeds the max value listed in your inventory). When this happens, your O2 supply will go from only depleting when jumping and running to depleting when walking as well. You also can’t fast travel in this state, so you’ll need to walk from place to place.

How Can I Reduce My Mass in Starfield?

If you want to lower your Mass, there are a few things you can do. The obvious choices are to either drop or sell some of the items you have in your inventory. Another great way is to offload some of your precious cargo into either your ship’s Cargo Hold or, more conveniently, in your companion’s inventory. To do the latter, speak to your active companion and select the option “Let’s trade gear.” You can’t give the companion more than their own Mass value, so be sure to clear their inventory out every once in a while.
