How to Leave a Sign
In Death Stranding, you can leave signs that will alert fellow players of danger, show them the best path up a mountain, or call out the existence of collectibles. These digital signposts are one of the many ways players can connect and help one another throughout their long journey across the country.
To leave a sign, hold the L1 (PS4) / LB (Xbox One) button, and then press Triangle. The game will freeze time and bring up several lists of signs you can leave. These signs are incredibly helpful in the early game, especially for players who aren’t familiar with the land yet. Help your fellow Sams, Sam!
