Hello everyone!
Since the demo’s release, 6,000+ players have joined the game and shared many valuable insights. Some veterans have already logged dozens or even hundreds of hours! We’re both amazed and grateful.
One of the most requested features has been co-op, and we’ve finally made it happen! The Duo co-op mode is now available! The game is also joining Steam Next Fest this week with this new demo, so grab a friend and survive together!

We’ve also made a short animation for the game. You might have seen a portion of it during the Convergence Showcase, and here is the full version!

About the Demo
For new survivors: the demo includes almost all early-game content across the first two maps, Savage Outskirts and No.6 Middle School, and now supports Duo co-op. Playtime typically ranges from 5 to 10 hours, depending on your pace. (You can also check other players’ reviews for reference.)
If you’d like to share your thoughts after playing the demo, we’d love to hear them. Every review helps!

Co-op was something we’ve always dreamed of doing, and also one of the most technically challenging features. We want players to be able to fight side by side with a friend, or just watch them get chased by zombies, lol.
The demo currently uses P2P connection, so stability may vary depending on the host’s connection. Since the feature is still new, there may be a few rough edges. Please feel free to join our official Discord server and report issues. We’ll work on fixing them as soon as possible!
