This is the second part of a multi-part RAR archive (usually denoted as part1.rar , part2.rar , etc.).
To extract or install the game, you typically need all parts (part1, part2, etc.) to be in the same folder, and you must use an archive tool like WinRAR or 7-Zip on the first file ( part1.rar ) to extract the full game data.
These files are used to split a large game installation into smaller, manageable chunks for downloading.
If this file was not downloaded directly from an official distributor (like Steam or Reiza Studios ), it is highly recommended to run a security scan (e.g., using VirusTotal ) before attempting to extract it, as files from unofficial sources can sometimes carry risks. To tell you more, please share: Where did you download this file from? Do you have the other parts (e.g., part1.rar ) already?
If you have all parts, I can help with the next steps to get the game running.
