Is the ONTOS repack safe to download?

Yes. Each ONTOS repack on Repack Games is scanned with VirusTotal before release; the scan link is included on this page. Some antivirus engines flag installer compressors (UPX, MPRESS) as heuristic threats — that is a known false positive for compressed executables, not a real infection.

Will the ONTOS repack work on Windows 10 and Windows 11?

Yes. ONTOS repack supports Windows 10 (build 1909 or later) and Windows 11 (64-bit). 32-bit Windows is not supported. macOS and Linux are not supported by repacked builds — use the original publisher's release for those platforms.

What is included in the ONTOS repack?

The repack includes the base game files plus any DLC/expansion packs released up to the build date listed at the top of this page. The repack is pre-cracked and pre-installed — no separate crack download is needed. File integrity hashes are verified by the repacker before upload.

Can I play ONTOS multiplayer or online with this repack?

No. Repacks are designed for single-player and offline modes only. Online multiplayer requires a legitimate copy purchased from Steam, Epic, GOG, or the publisher's store, since multiplayer requires authenticated accounts and DRM tickets.

How do I update ONTOS when a new patch is released?

Repack Games periodically posts update patches as separate downloads on this page. Check the page's update history (above) for the latest patch link. Apply patches in numerical order (1.01, 1.02, 1.03 etc) on top of the base repack — do not skip versions.
