How to Repair Items
You Can Repair Items You’re Carrying. Early on in Death Stranding, it seems like the best way to use repair spray to fix your item containers is to set them all on the floor. Then you use repair spray the traditional way: by equipping it and using the triggers to fire.
There’s a faster way, though. While holding repair spray, you can use the square (PS4) / X (Xbox One) button to fire it off behind behind you, repairing anything on your back. This won’t work on items on your shoulders, but it’s a much faster way of repairing things than unloading and putting it all back on again. That’s especially true when you’re out in the open.
