These are underrated online co-op indie games: titles with strong reviews but not yet the audience they deserve. indielist surfaces 14 online co-op games that each hold at least 80% positive Steam reviews while staying under 5,000 total ratings : the sweet spot where a game has proven itself with real players but hasn't broken out yet.
