Mob Special


 * A powerful .45 caliber machine gun that fires
 * infinite bullets! Fire away! Chicago—style.

The Thompson submachinegun, also caled Tommy Gun or Chicago Typewriter is a .45 Caliber automatic weapon. It has been made popular by its noted uses by American gangsters during the prohibition era, as well as by allied forces during World War 2.

Resident Evil 4


The Chicago Typewriter is an infinite-ammo sub-machine gun based on the Thompson M1A1. In the GameCube version it is available for 1,000,000 pesetas after beating the Assignment Ada minigame. In PlayStation 2, PC and Wii versions, beating Separate Ways will unlock this gun for the main game, while beating Assignment: Ada will unlock it for Separate Ways, where it costs 300,000 pesetas. In the main game it also costs 1,000,000 pesetas.

The Chicago Typewriter takes up 21 spaces (7x3) of Leon's inventory, making it one of the bulkiest weapons in the game. It is equivalent in size to the P.R.L. 412.

It has a firepower of 10.0 and can fire every 0.10 seconds, effectively doing 100.0 damage per second. It has an infinite magazine (infinite ammo, no reloads), yet can be "reloaded" for fun, taking 2.83 seconds. When Leon wears his Mobster costume, reloading has a special animation (See Notes) and his Typewriter becomes the M1921 model with a foregrip and 50-round drum magazine. Otherwise, the Chicago Typewriter's skin is the M1A1 Thompson famous for it's use in World War II, using a 30-round box type magazine.

The Chicago Typewriter cannot be upgraded (because when it is bought it is already fully upgraded).

The Chicago Typewriter is extremely powerful. With its high damage and rate of fire, coupled with its infinite ammo and ability to be endlessly fired, it is generally considered to be one of the most effective weapons in the game. Much like the Red9/Blacktail debate, there is an ongoing debate as to whether the Chicago Typewriter is more effective than the other "special" weapons, the Infinite Rocket Launcher and the Handcannon A typical Ganado will die from one or two shots from the Typewriter, making entire crowds fall in seconds, and bosses such as the first El Gigantes Leon encounters take a similar amount of time to kill.

Resident Evil: Operation Raccoon City
The Thompson returns in Operation Raccoon City, this time refered to as the 'Mob Special.' It was first seen on a website for Kendo's Gun Shop, which is linked to Inserted Evil. It is also seen in some released gameplay footage. The weapon depicted has traits of both versions of RE4: It resembles Leon's model with the drum magazine of Ada's. It is currently unknown whether it can be found within the game's storyline, or is a post-game reward as it was in Resident Evil 4. It is however, visible being used in the multiplayer trailer.

Trivia

 * During the Prohibition era (1920s) in Chicago, America, the Thompson Sub-Machine Gun was legally and easily available in Sporting Goods shops and as such was popularly used by the Chicago mob and the Police. It was said to sound like a typewriter when it was heard firing at a distance. Thus the Thompson earned the name "Chicago Typewriter".
 * The Thompson also became synonymous with various career criminals such as John Dillinger, Lester "Baby Face Nelson" Gillis, and George "Machine Gun" Kelly Barnes. This popularity among the criminal underworld in conjunction with its frequent use by law enforcement earned it the title of "the gun that made the 20's roar".
 * Despite being a notorious icon of the 1920s, the Thompson would later become the military-issued submachine gun for the United States Military during World War II. The M1 and M1A1 models of the Thompson saw action in both the European and Pacific theaters throughout the course of the war, issued to British and Canadian commandos units, American paratroopers and ranger battalions. Its power in Resident Evil 4 is equivalent to the historical fact that the Thompson was praised for having more stopping power than sub machine guns of other nations.
 * The 1921 model was capable of firing up to 1000 rounds per minute at a range of 165 yds, and can be loaded with 100 round drum magazine.
 * The 1928 model has slower rate of fire, about 650 rpm, can be loaded with 50/100 round drum magazine, or 20/30 round clip magazine. Along with M1/M1A1 model, the 1928 model is used by U.S. military during World-War II.
