Best co-op action games by platform
Best co-op action games on PC
PC has the broadest action-co-op range in this evidence set, from Helldivers 2 and Deep Rock Galactic to Left 4 Dead 2 and Halo: The Master Chief Collection. If your group values flexibility, performance tuning, and a deep library, PC is the easiest place to build a co-op rotation.
Best co-op action games on PS5
For PS5, Helldivers 2 is the standout action-first pick, especially if your group likes high-tempo missions and clear team roles. Deep Rock Galactic is also a strong option for players who want mission-based teamwork and replayable squad play.
Best co-op action games on Xbox
Xbox players get a strong co-op lineup through Deep Rock Galactic, Halo: The Master Chief Collection, Fortnite, and World War Z: Aftermath. If your group splits time between console and PC, the Microsoft ecosystem options are especially practical.

| 4 players | Helldivers 2, Deep Rock Galactic, Left 4 Dead 2, World War Z: Aftermath | The sweet spot for chaotic action, mission coordination, and repeatable sessions. |

What to revisit before you buy
- Crossplay status changes, especially after updates or new platform support announcements.
- New ports and platform expansions for PC, PS5, Xbox, and Switch.

- New co-op action releases that may displace older entries on your shortlist.
A practical way to choose your next co-op game
If your group is split across platforms, start with crossplay first and genre second. If everyone is on the same ecosystem, then player count and session length matter more. Four-player squads usually get the most out of mission-based action games, while duos may prefer tighter experiences that keep every player engaged. For longer repeat sessions, look for games with clear roles, strong matchmaking, and enough mission variety to stay fresh over time.
