If you want another co-op session with the teamwork, tense movement, and unpredictable mishaps of PEAK, start with R.E.P.O. for physics-driven horror or Lethal Company for scavenging under pressure. They are not climbing games, though: each recommendation below matches a different part of PEAK’s appeal, and the closer alternatives need a check of their current official listings before you buy.
What makes a game feel like PEAK?
PEAK is a co-op climbing game built around the danger of a small mistake. Its Steam listing describes friends-only multiplayer for up to four players total, with solo play also available. That combination—working together through precarious movement and seeing how a group attempt unfolds—is a more useful comparison point than the broad label “co-op.” Check PEAK on Steam.

The alternatives here range from verified physics or scavenging games to titles suggested by players looking for a similar co-op feel. They are not all mechanically equivalent. In particular, the available details confirm specific features for PEAK, R.E.P.O., and Lethal Company; for the other three, consult the official listing for current modes, player limits, platforms, and development status.
Games like PEAK: quick comparison
| Game | What the available details establish | Best fit if your group wants | Important distinction or check |
|---|---|---|---|
| PEAK | Co-op climbing; friends-only Steam multiplayer for up to four total players, or solo play. | The baseline: teamwork and risky climbing. | Steam listing: official store page. |
| R.E.P.O. | Online co-op horror with physics and proximity voice chat; up to six players, according to Steam. | Group physics chaos with a horror edge. | It is a horror and scavenging game, not a climbing game. Steam listing. |
| Lethal Company | Co-op scavenging on abandoned moons to meet a quota; Steam marks it Early Access. | Exploring together under pressure. | Its focus is scavenging, and Early Access status can change. Steam listing. |
| Content Warning | Named as an adjacent co-op suggestion; current mechanics and player limits are not established here. | A candidate to investigate if your group wants another social co-op game. | Check the official listing for its current features, platforms, player count, and status. |
| Chained Together | Suggested by players seeking alternatives; current group mechanics are not established here. | A title to compare against your group’s preferred kind of co-op challenge. | Verify its official listing before assuming how its multiplayer works. |
| Human: Fall Flat | Suggested as a co-op option in a PEAK-adjacent grouping; current modes and limits are not established here. | A possible physics-oriented alternative to investigate. | Check supported platforms, co-op modes, and player limits on the official listing. |
1. R.E.P.O. — for physics chaos with a horror edge
R.E.P.O. is the clearest pick if your group wants online cooperation plus unpredictable physics. Steam describes it as a co-op horror game with physics and proximity voice chat for up to six players. That larger stated group limit may suit a group that cannot fit into PEAK’s four-player total, but the experience shifts from climbing to horror and scavenging. See R.E.P.O. on Steam.

2. Lethal Company — for exploration under pressure
If your group enjoys exploring together while managing a shared objective, Lethal Company is a promising adjacent choice. Steam describes its loop as scavenging abandoned moons to meet a quota. That creates a different source of tension from a dangerous climb: the premise centers on collecting what the group needs to reach its target. Steam lists the game as Early Access, so check the store page for its current status and details before purchasing. See Lethal Company on Steam.
3. Content Warning — a community-suggested adjacent option
Content Warning appears in player suggestions for creative co-op games and is also named in a Steam announcement about PEAK. That establishes it as an adjacent recommendation people bring up, not as a confirmed mechanical match. The available information here does not establish its current gameplay details, player limit, platform availability, or development status; check its official listing against what your group wants before deciding.
4. Chained Together — check whether its co-op fits your group
Chained Together is another player-suggested alternative, but the available details do not establish its exact group mechanics. Do not choose it on the assumption that it shares PEAK’s climbing loop or invite model. Review its official listing for how co-op works, how many people can play, supported platforms, and current status.

5. Human: Fall Flat — investigate it for physics-oriented co-op
Human: Fall Flat has been suggested as a co-op option in a grouping of physics and party games adjacent to PEAK. That makes it worth checking if your group is looking for a different kind of physical comedy, but current co-op modes, player limits, and supported platforms are not established here. Confirm those details on its official listing before treating it as a fit for your setup.

6. RV There Yet? — a broader party-game possibility
RV There Yet? is named among multiplayer party games, but the available information does not verify it as a close PEAK match or establish its current features. Treat it as a broader candidate rather than a direct substitute. Check its official listing to see whether its actual multiplayer and core activity suit your group.
How to choose for your group
- Want the closest confirmed match in teamwork and precarious movement? Stay with PEAK; it is the only game in this list whose confirmed premise is co-op climbing.
- Want physics-driven co-op and accept horror? Consider R.E.P.O.; Steam states its online player limit and proximity voice chat features.
- Want exploration with a shared objective and a horror tone? Consider Lethal Company, keeping its Early Access status in mind.
- Considering one of the other three? Verify the current official listing for the exact feature that matters to your group—player count, co-op mode, platform, or status—rather than relying on a community comparison.
Store pages can change, particularly for games in active development. The listed release date for PEAK is June 16, 2025; that date does not make every alternative’s current features or status a fixed fact.
