What to check when co-op or the demo will not connect
- Check the live demo count above. Normal numbers mean Steam is up.
- Check Steam itself. A Steam-wide login/store/friends problem takes the demo down with it; steamstat.us tracks it.
- Update the demo. A version mismatch is the most common co-op failure.
- Restart Steam on both machines.
- Read the latest patch notes (linked above). The demo has had EOS/networking fixes.
- Check your firewall and allow the demo through Windows Defender.
This is the demo, not the full game
The full game launches in Early Access on November 25, 2026. Its player count will be on appid 4009490; until then, this page tracks the free demo (appid 4601500). After launch, we will switch the card to the full game and keep the demo number as a comparison.
How this page works
The number comes from the official Steam API through our cached endpoint, refreshed every 5 minutes. We do not copy numbers from other sites or guess at outages; if the API does not answer, the card says so.
