Your first opportunity to pick up this weapon is near the Electrical Override switch in the Medical Pavilion’s Emergency Access corridor.

Ammunition

Machine Gun Rounds: These .45 caliber bullets will do the job you want, if the job is spraying death at your enemies. Hey, someone has to do it.
Carry/Load: 360/40

Antipersonnel Auto Rounds: These .45 caliber bullets are specifically designed to neutralize non-armored targets like Splicers. Or clowns.
Carry/Load: 180/40

Armor-Piercing Auto Rounds: These .45 caliber bullets are particularly effective against metal or armored targets, like turrets, security bots, and all variations of the Big Daddy.
Carry/Load: 180/40

Upgrades

Damage Increase: An acceleration framework increases the damage of the Machine Gun. I wouldn’t recommend taking either of the Machine Gun’s upgrades until you’ve taken most of the others.

Kickback Reduction: A stabilization cylinder reduces the kickback of the machine gun. I wouldn’t recommend taking either of the Machine Gun’s upgrades until you’ve taken most of the others. This should be your first choice of the two, though.
