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, and not two duo lobbies counted as a four-player night.
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.
Five in one session? Use the five-player PC list - titles that fit five without inventing a second lobby. Or browse PC co-op by genre.
Four friends, mixed stores?
See overlap across linked libraries, then lock game and time in Discord.
