Action Online Co-op Games on Steam
Games sitting in the overlap between Action and online co-op â the two filters most groups actually care about at once. Steam's own store makes this intersection awkward to search for, because genre and multiplayer mode live in separate filter systems.
For what to check before committing to one of these, see the full Online Co-op guide.
