Compressing a ~12 GB modern game down to 900 MB (a 92% reduction) is practically impossible for a playable version of the game. Files that claim this usually contain:

Sites like "techs4best" that promote "100% working" highly compressed files are not verified sources. Downloading from such sites puts your personal data and hardware at risk.

The archive may be filled with useless data or "dummy" files that do nothing.

In rare cases where compression is "real," all audio, cutscenes, and high-resolution textures are removed, making the game unplayable.

For a safe and functional experience, you should download the game from official storefronts like the Ubisoft Store , Steam , or GOG. Actual System Requirements
