The Colt Commando is the most powerful firearm in Max Payne. It is an assault rifle designed to increase Max's firepower along with Ingrams and Pump-Action Shotguns. It becomes available for the first time in Part II, when Vladimir Lem suggests Max find Boris Dime's ship, eliminate him and his crew and seize the powerful weaponry stored in the hold: here Max will find many Colt Commandos.
The Colt Commando assault rifle shares many aesthetic traits with the M4 Carbine, which is derived from. In Max Payne 2, in fact, the Colt Commando's role is played by the M4. The rifle offers lots of advantages: it is compact (more than the M4), accurate and has a capacity of 30 rounds (only Ingrams have a bigger magazine size); however, it doesn't have the excellent fire rate and damage of Max Payne 2's M4, since - some said - it fires slightly weaker and less straight bursts. These lacks, along with the Ingrams' effectiveness (better than in Max Payne 2), don't make the Colt Commando the great and absolutely reliable gun that is M4, whose values certainly win the competition with the Kalashnikov.
Nevertheless, the Colt Commando is a very good weapon, very useful for overcoming the attacks of Punchinello's goons: it's Lem who warns Max about the need of suitable guns to defeat Punchinello. This rifle is also very helpful during the hard battles with Cold Steel's and Aesir Corporation's security guards, who also make a massive use of this weapon.
The Colt Commando is chambered for Colt Commando ammunitions and Max can carry around 150 rounds; ammo becomes much more abundant in Colt Steel's and Aesir Corporation's rooms. It can be found in sole Max Payne.
