The following examples are intended to remind developers that 1) prosocial actions do happen frequently in games, and 2) we create environments that generate them more than we realize.
This list is going to grow as we discover new examples, so we encourage you to bookmark this page and check back often!
1. Dropping ladders and likes in Death Stranding
In Death Stranding, helping yourself can often help others. For example, leaving a ladder in a place that’s difficult to cross can help players in other worlds. They, in turn, can indicate their appreciation for your prosocial behavior with a like.

2. Leaving messages in Dark Souls 3
Dark Souls 3 allows players to leave notes for other players in different worlds, giving them tips on the environment (or sometimes misleading them).

Though the prosocial behavior is technically exhibited by those who answer the call, Wild Hearts makes it easy to request assistance from strangers when a player is facing particularly challenging monsters.
