Modern CoD titles like Modern Warfare III or Warzone are notorious for being massive (often 100GB to 200GB+). A RAR archive promises to "shrink" that download, making it more manageable for those with slower internet.
Older CoD titles frequently go on sale for 50-67% off during seasonal events.
Most RAR downloads are "cracked" versions. This means you lose out on the heart of the Call of Duty experience: Multiplayer and Progression. You are usually limited to the offline Campaign or local Bot matches.
Even if the download finishes, you then have to extract it. This requires significant temporary disk space (the size of the RAR + the size of the uncompressed game). If one "part" of a multi-part RAR is corrupted, the entire download is often useless.
Searching for "download-call-duty-rar" is a high-risk activity for your hardware and data.
Users are often looking for "repacks" or cracked versions of older titles (like Black Ops II or the original Modern Warfare ) that may no longer be easily available or are still priced high on official storefronts. The Reality: A Mixed Bag of Frustration
