"That's No Sandstorm" was a planned campaign mission in Call of Duty 4: Modern Warfare. The only proof of its existence is a file called "compass_map_sandstorm.iwi" present in the game's source files. In the mod tools, in the raw/English/localizedstrings folder, a file called "sandstorm.str" can be found. The string file includes information about the level, such as its location, the level name, the date, and various objectives.
