PEAK is a co-op climbing game about a group of lost nature scouts trying to escape a mysterious island by reaching the mountain at its center. You can attempt the climb alone or bring friends, but cooperation is central to the group route: scouts can help one another up ledges and set ropes or climbing spikes for those following. Proximity chat supports communication as teammates coordinate their ascent.
The mountain puts survival pressure on that teamwork. Its four biomes contain life-threatening obstacles, while scavenged food and carefully managed injuries matter because setbacks reduce stamina and make climbing harder. Survival items, including energy drinks and climbing spikes, offer ways to prepare, but the route remains a test of both individual condition and group support. The island layout changes every day, and the same island can also be attempted more than once within a day.
Multiplayer is friends-only, with invitations through Steam for up to three other scouts. A count therefore provides context for the pool of people playing, but it does not by itself show how many are climbing together, since a session can be solitary or shared with invited friends.
