PC co-op games for four players
The default squad size for many PC friend groups — if the lobby actually fits four.
Read this before the list
Player limits vary by mode, DLC, and patch. Confirm the co-op lobby cap on the Steam or Epic store page before you buy for the group.
These picks assume four players in one lobby tonight — not a larger Discord server where only part of the group plays.
Ownership matters more than hype: everyone needs a copy on a store they can launch from PC.
Solid four-player picks on PC
- Deep Rock Galactic — four dwarves is the default squad size.
- Helldivers 2 — up to four in a squad; popular for weekly friend groups.
- Lethal Company — up to four in a ship; chaos scales with headcount.
- Overcooked! 2 — up to four players; short sessions fit weeknights.
- Left 4 Dead 2 — up to four in co-op campaign; still a reliable squad night.
When the store says co-op but means two
Some tags mean two-player online co-op only. Read the multiplayer section, not just the marketing banner.
Four friends should shortlist from ownership overlap, not a backlog poll.
