PEAK is a lot more fun when everyone is climbing together.
It is also a lot easier to plan a mountain expedition when your friends are actually on the same platform.
Fortunately, that is no longer necessary.
With the arrival of PEAK on consoles, crossplay is now live. PC players can climb with friends on PlayStation 5, Xbox Series X|S and Nintendo Switch 2, while the game keeps its simple room-code system for bringing everyone into the same lobby.
There is one important catch, though.
Your progress does not follow you from one platform to another.
If you are trying to figure out how PEAK crossplay works, how to invite friends, which platforms can play together and what happens to your progress, here is everything you need to know.
Quick Summary
- PEAK supports crossplay between PC, PS5, Xbox Series X|S and Nintendo Switch 2.
- A PEAK lobby can hold up to four players.
- Cross-platform groups can use room codes to join the same lobby.
- The host creates a lobby and shares the room code with friends.
- Friends enter the code through Join Game.
- Steam progress does not transfer to other platforms.
- Badges and other progression need to be earned separately on another platform.
- PC mods are not officially supported when playing with console players.
- PEAK’s mountain changes regularly, so every group still has to adapt to the run in front of them.
Is PEAK Crossplay?
Yes.
PEAK has full crossplay between its supported PC and console versions.
That means a player on Steam can join friends playing on PS5, Xbox Series X|S or Nintendo Switch 2.
The same cross-platform setup also works between the supported console platforms.
So if your group is split across different systems, you do not need everyone to move to the same platform just to start a climb.
That is particularly useful for PEAK because the game is built around small cooperative groups rather than huge multiplayer lobbies.
Which Platforms Can Play PEAK Together?
The current crossplay group includes:
| Platform | Crossplay | |
|---|---|---|
| PC / Steam | Yes | |
| PlayStation 5 | Yes | |
| Xbox Series X | S | Yes |
| Nintendo Switch 2 | Yes |
There is one detail worth remembering: Nintendo Switch 2 is the supported Nintendo console version.
The crossplay system is designed to put players from these supported versions into the same PEAK sessions.
How to Play PEAK With Friends on Different Platforms
PEAK does not require you to figure out which platform account your friend uses before creating a group.
Instead, the game uses room codes.
The process is simple.
Step 1: Create a Lobby
One player starts a multiplayer lobby in PEAK.
That player becomes the host for the session.
Step 2: Find the Room Code
Once the lobby is created, the room code can be found through the game’s lobby interface.
The host can copy the code and send it to the other players.
Step 3: Share the Code
Send the code to your friends through whatever communication method your group normally uses.
The important thing is that everyone has the correct room code.
Step 4: Choose Join Game
The other players open PEAK and select Join Game.
They enter the room code supplied by the host.
Once everyone is inside, the group can begin the climb.
The system is especially useful when friends are using different platform ecosystems because you do not have to rely entirely on one shared friends list.
How Many Players Can Play PEAK Together?
PEAK supports up to four players in a cooperative group.
That means you can have yourself plus three friends on the same expedition.
The four-player limit remains the same whether everyone is playing on one platform or the group is completely mixed.
A PC player, PlayStation player, Xbox player and Switch 2 player can therefore form one four-person climbing team.
And PEAK gives every member of that team a reason to pay attention.
One player might find a useful item. Another might place climbing equipment. Someone else might be injured and need help getting through the next section.
Splitting up is easy.
Getting everyone back together can be considerably harder.
Does PEAK Have Cross-Progression?
This is where crossplay and cross-progression become two very different things.
PEAK does not currently transfer Steam progress to other platforms.
If you have already earned badges on PC and then start playing on another supported platform, those achievements do not simply follow your account.
You will need to earn the relevant progression again.
That can be frustrating for players who have already spent a lot of time climbing on Steam, but it is important to know before switching platforms.
Crossplay lets you play together.
It does not mean your progression is shared across every version.
What About Voice Chat?
PEAK is built around communication.
The game supports proximity chat, which makes distance between players part of the experience.
That can become surprisingly important during a climb.
Someone may be waiting around a corner. Another player may have found an item. A teammate might be struggling to reach the next ledge.
Because the mountain can separate players physically, communication can be just as important as the climbing itself.
The crossplay system does not change that basic idea.
Your friends are still your biggest advantage.
Can You Play PEAK Solo?
Yes.
PEAK can be played alone.
That does not make the game easier, though.
Without teammates, there is nobody around to give you a boost, carry equipment, help with difficult sections or rescue you when a climb goes wrong.
Solo play can actually make the game’s survival systems feel more demanding because every mistake belongs to you.
For new players, playing with friends is usually the easier way to understand how the game’s climbing and survival systems work.
Why the Daily Mountain Matters
PEAK isn’t built around memorizing one permanent route.
The mountain changes regularly, which gives each run its own problems.
Your group may know how a particular obstacle works, but the next expedition can still force you to rethink your route.
That becomes even more interesting with crossplay.
A new player joining from another platform may know very little about the current mountain. An experienced player can act as a guide, but nobody can completely remove the unpredictability from the climb.
That is part of what makes PEAK work so well as a cooperative game.
Survival Matters More Than Speed
New cross-platform groups can make one common mistake: treating PEAK like a race.
It isn’t.
Getting ahead of everyone else does not help much if the rest of your team cannot follow.
Injuries can reduce your stamina and make later sections harder. Supplies matter. Climbing equipment can turn a difficult route into a manageable one.
A good group should therefore think about the whole team rather than the fastest individual player.
Sometimes waiting for your friend is the smartest move you can make.
Common PEAK Crossplay Mistakes
Using the Wrong Room Code
Make sure everyone is entering the current code from the host’s lobby.
Assuming Progress Transfers
It doesn’t. Your platform progression remains separate.
Playing With Unsupported Mods
PC players should be careful when joining console players with mods installed. The developers do not officially support mods in cross-platform sessions and recommend playing without them when troubleshooting multiplayer problems.
Splitting the Team Too Far
PEAK makes exploration tempting, but moving too far apart can leave one player dealing with an obstacle alone.
Treating Every Run the Same
The changing mountain means yesterday’s successful route may not be the best answer today.
What If PEAK Crossplay Isn’t Working?
Start with the simplest checks.
Make sure everyone is running the current version of the game. Then create a fresh lobby and generate a new room code.
If a PC player is using mods, remove them before testing the crossplay session again.
It is also worth checking that the room code has been entered correctly. A single incorrect character is enough to keep someone out of the lobby.
Finally, remember that a new cross-platform launch can bring temporary connection problems as large numbers of players join at once.
If everything looks correct but the session still refuses to work, restarting the game and creating a new lobby is a sensible first step.
The Best Way to Start a Crossplay Run
If your group has never played together before, don’t make your first expedition unnecessarily complicated.
Start with four players if possible.
Use the room code to get everyone into one lobby, then spend the first part of the climb learning how your group communicates.
Don’t rush ahead.
Share useful items.
Help injured players.
Learn how climbing equipment works.
Most importantly, pay attention to what causes your team to fail.
PEAK becomes much easier once everyone stops treating the mountain as four separate solo challenges.
It is one climb.
PEAK Crossplay Makes the Game Easier to Recommend
The biggest advantage of PEAK’s crossplay system is simple: your friends no longer need to own the game on the same platform to climb together.
PC, PlayStation 5, Xbox Series X|S and Nintendo Switch 2 players can form one four-person team.
The room-code system keeps the process straightforward, while the game’s changing mountain ensures that cross-platform multiplayer does not remove the survival challenge.
Just remember the biggest limitation:
Crossplay is shared. Progression isn’t.
Your badges and progression stay tied to the platform where you earned them.
Once your group understands that, getting everyone onto the same mountain is remarkably simple.
And in PEAK, reaching the top is only half the challenge.
Getting there without leaving your friends behind is the real test.
