A legitimate build of this game at v0.7.1 should typically be several gigabytes. If the .zip is unusually small (e.g., under 100MB), it is likely a downloader/malware stager.
Proceed with extreme caution. Unless you can verify the file came directly from the developer's authorized platform, treat it as a high-risk file.
Upload the .zip file (or the .exe once extracted) to VirusTotal . It will scan the file against 70+ antivirus engines.
Files with "Hentai" or "VR" in the title are common targets for "re-packers" who may inject adware, miners, or trojans into the .zip .
If you must run it, use a sandbox environment like Windows Sandbox or Any.run to see if the program attempts to make unauthorized network connections or modify system files.
.zip (typically containing an executable like HentaiFightersVR.exe and Unity data folders)
Because this file is often distributed through third-party hosting sites (like Mega, MediaFire, or niche forums) rather than official storefronts like Steam or Oculus, it carries a higher risk profile.
