PC is where most co-op happens: the biggest catalog, the cheapest sales and the easiest way to check whether your machine can actually run something. These games are recorded in our catalog as available on Windows, Mac or Linux.
Availability is not the same as compatibility — check the requirements page on any game before buying if your hardware is older.
Everyone on a different platform? Post what you own and Co-Op Now finds the games your whole group can actually play.
Platform availability recorded in our catalog. 400 games currently qualify, showing the top 60.




























































Each game in our catalog carries a recorded store platform list. A game appears here only when this platform family is on that list — we never infer availability from a tag, a title or a store blurb, and games with no recorded platforms are left out rather than guessed. Party sizes on the cards come from our canonical same-group data, not from lobby or server capacity, and crossplay is tracked separately because availability on two platforms does not mean the two can play together.
Most are. Our catalog is Steam-first, so PC availability usually means a Steam release; individual game pages link out to where you can buy it.
Only when the game supports crossplay. Each game page records crossplay separately, and our crossplay hub lists the games where it is confirmed.
Platform availability comes from the store data recorded in our catalog, not from user guesses. Games without a recorded platform list are left off these pages instead of being estimated.
Co-Op Now reads what everyone actually owns, checks the real party size, and locks in a session everyone can make.
