"All Ghillied Up" is a level in the 2007 first-person shooter video game Call of Duty 4: Modern Warfare and its 2016 remastered version, Call of Duty: Modern Warfare Remastered. Set in Pripyat, Ukraine in 1996, the player assumes control of then Lieutenant John Price and is assisted by their superior Captain MacMillan. The pair make their way through Pripyat covertly with the objective of assassinating the game's primary antagonist, Imran Zakhaev. The player may deal with enemies stealthily, overtly, or avoid engaging them altogether.
The name refers to the ghillie suits worn by Price and MacMillan in the mission. It was designed by Mohammad Alavi initially in secret due to the difficulty of explaining its intricacies to the artificial intelligence (AI) programmer. It took Alavi three months and more than 10,000 lines of code to make the first minute of gameplay for the level. "All Ghillied Up" was praised for its atmosphere, pacing, and freedom of choice, and has since been considered by critics to be one of the greatest levels in video game history.
