All Steam co-op games by mode (no review floor)
- 16,486 rows
- updated October 5, 2026
- CC BY 4.0
Every Steam game in the imho.run catalogue with a genuine co-op Steam category, with no minimum number of reviews, each classified by how the co-op is played: online, local (same screen / split screen) or both. It uses the same rules as the 500+ review dataset, so most rows are small and new games with few or no reviews yet. Columns: app ID, name, our page URL, mode, release year and a review-count bucket from <10 to 20k+. Updated daily.
Online: 10,853 · local: 3,951 · both: 1,682

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. 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.
- There is no review floor: a game with no reviews yet is in, with the bucket <10. Upcoming games with a co-op category are included too.
- LAN-only games, adult-only games, DLC, software and games removed from the Steam store are left out. Games our catalogue has not fetched store details for yet are missing until it does.
