How it is built
- A game counts as co-op only with a genuine co-op Steam category: Co-op, Online Co-op, LAN Co-op or Shared/Split Screen Co-op. A bare Multi-player or PvP category does not count.
- Online: the Online Co-op category, an MMO, or the Online Co-op community tag; or a bare Co-op category with no sign of local play at all (Borderlands 2, Left 4 Dead and Dark Souls III only carry Co-op).
- Local: Shared/Split Screen Co-op, or any co-op category plus the Local Co-op tag. Remote Play Together alone is not online co-op: it streams a local game.
- Games that are LAN-only, adult-only, DLC or under 500 reviews are left out.
