The Ingram MAC-11 is an American .380 caliber automatic machine pistol. It is seen in Incident: 110A, in the hands of an agent, powerless against Jesus's powers. It is then seen in Incident: 1000A with a suppressor, at the hands of another agent who is once again swiftly defeated by Jesus. It is seen held by more agents in ANAMNESIS.fla and DedmosRebuilt.fla, who are shot to death by Deimos before they can fire. The latter's M-11 had a distinct trigger guard.
In Madness: Project Nexus (Classic), the M-11 is a purchasable weapon in the Arena Mode as one of the 4 weapons with the fastest rate of fire, along with the Steyr TMP, Minebea PM-9, and Colt M-16. With its spare 3 magazines, it has the most ammo out of all the SMGs in the game.
The weapon makes a return to the sequel, MADNESS: Project Nexus as the Automatic Pistol MK.11 (though still carrying the term MAC-11) as a very common Sub-machine gun that can be often found flying around, in containers, or in the hands of many different factions. In Arena Mode, it is unlocked for purchase after the completion of The Goods and has third highest capacity in it's category. It is commonly used by MERC Gunners in both campaign and Arena.
