PEAK LFG for the climb up the mountain. AnySquad shows live lobbies looking for a co-op group to scale PEAK's biomes together — sharing stamina items, rope tricks and the inevitable falls that solo climbers do not recover from as easily.
PEAK's physics-based climbing punishes a lone player hard — no one to catch a fall, share a scouted route, or split the items that make later biomes survivable. A full group turns a mountain that ends most solo runs early into one that actually gets climbed.
PEAK is developed by Team PEAK and published by Aggro Crab and Evil Landfall?. It has been on Steam since 2025. Multiplayer listed on Steam: online co-op. 94% of its 308,116 Steam reviews are positive. It is Verified on Steam Deck.
A duo is the easiest way to play PEAK with someone better than a random fill — one person you can actually talk to. For a full squad, post the slots you still need: a post that says what it is missing gets answered faster than a profile that lists what you play.
PEAK posts on AnySquad are tagged by platform, so every post you see is one you can play with.
Say how many players you need, when you play, and the one thing you care about — a mic, a rank, a region or just no raging. Leave out the rest: a short post gets answered, a list of requirements gets scrolled past. Once your group is set, close the post.
Yes, hosts note whether they are starting a new run or continuing one, so you can join at a compatible point.
Most lobbies look for a full group of up to four — check each listing for exactly how many slots are open.
