“Steam-Rip” generally refers to a cracked copy of a game that has been stripped from Steam’s DRM (Digital Rights Management). “Ksenia” is a name associated with some cracking groups, but it’s also often faked by malicious uploaders. These files are not official, and there is no verified safe source.

> Ksenia: The Premium Edition includes one feature Microsoft never finished. The ability to drive into other players' realities. Look behind you.

If you only care about the base map, buy the Standard Edition for $59.99 (or ~$30 on sale). You can always add expansions later.
