Legitimate modern games are rarely distributed via random .rar files on third-party hosting sites. If you didn't download this from a verified storefront like Steam or GOG , it is likely a "repack" at best or a virus at worst.
Opening or extracting a .rar file can sometimes trigger scripts or reveal executable files ( .exe ) that infect your system the moment you run them.
If you’re looking to play the real game, the best (and safest) way is to grab it on Steam, where it frequently goes on sale for a very low price.
Look at where you found the link. If it came from a YouTube description, a random Discord server, or an unverified "free games" site, it is almost certainly unsafe.
