You have three legitimate options to download Breakthrough today. None violate copyright, and all are safe.

Q: Is there a direct ISO download link for Breakthrough?
A: Not legally for free. The only safe, legal “download” is the GOG installer (not an ISO) or ripping your own CD. Any website offering a direct ISO without proof of purchase is pirating.

Q: Can I play Breakthrough without the base MoHAA?
A: No. Breakthrough requires the original Medal of Honor: Allied Assault installed first.

Q: Will the CD version run on Windows 11?
A: Not without patches (OpenMoHAA or widescreen fix). The SafeDisc DRM on original CDs is blocked by Microsoft since Windows 10.

Q: Is Breakthrough worth it for single-player only?
A: Yes. About 6–8 hours of new missions, including vehicle sections (jeep, tank) and the famous Anzio beach landing.
