The demo, rebuilt.

A few of you hit the same handful of problems with the old demo:

  • a separate launcher window that opened a new copy of the game every time you clicked Play;

  • "Could not find the Webview2 runtime"on Steam Deck and Linux;

  • runs where no anomalies spawned at all;

  • crashes on lower-VRAM laptops.

So we rebuilt it. The launcher is gone, the menu is in the game now. The anomaly RNG was rewritten. Virtual shadow maps and ray tracing are off by default for stability on smaller GPUs. Play the new demo: Backrooms Anomaly Demo Backrooms Anomaly releases this June! If you want to be notified on launch, wishlist the full game here.
