A 200MB file cannot contain 16GB of data. It defies the laws of digital physics.
First, one must address the fundamental laws of data compression. Call of Duty: Black Ops 2 , released in 2012 by Treyarch, is not a small game. A standard installation of the full title, including its single-player campaign, Zombies mode, and multiplayer assets, occupies approximately 15 to 18 gigabytes (GB) of storage space. In the world of computer science, lossless compression—the method required to run a game without losing critical functionality—has theoretical limits. Reducing a 15 GB game to 0.2 GB (200 MB) would represent a compression ratio of 99.6%. For context, even the most efficient archiving tools like 7-Zip or WinRAR might achieve a 10-20% reduction on game files, as many assets (textures, audio, video) are already stored in compressed formats. Achieving a 7,500% reduction is not advanced programming; it is a physical impossibility. Call Of Duty Black Ops 2 Highly Compressed 200mb
