Machine Gun

A Machine Gun is a fully automatic mounted or portable firearm, usually designed to fire rounds in quick succession from an ammunition belt or large-capacity magazine, typically at a rate of several hundred rounds per minute.

In United States gun law, machine gun is a term of art for any fully automatic firearm, and also for any component or part that will modify an existing firearm such that it functions as a fully automatic firearm.

In Mortal Kombat
The machine guns were still used by police forces in Earthrealm. Officer Kurtis Stryker also used this weapon in Mortal Kombat: Armageddon.
