The M590A1 appears frequently throughout the campaign. It is a common gun carried by HPD officers and the US Navy. In Cloak of Darkness, it can be seen used against the HPD by a pair of Separatists.

It is useable in Cloak of Darkness and Remember This Hour.


The M590A1 is the default shotgun unlocked. It is relatively easy to handle with good range and damage. Capable of benefitting from no attachments, the weapon is versatile enough to adapt to different playstyles of shotgun combat. It has the highest damage of the shotgun class.

Compared frequently to the RMB-93, the M590A1 has more damage, a higher magazine capacity, a quicker pump-action and is unlocked much earlier. These traits make it much more commonly found in multiplayer. The weapon is much more suited to an aggressive shotgun use while the RMB-93 seems to emphasize on single enemy combat.

The shotgun is tied for the second highest pellet spread of the shotguns, shared by the M1216 Tactical and being beaten only by the SPAS-15. This makes it possible to aim a good distance and get a chance of damaging enemies.

Combined with its fast pumping, the M590A1 can easily follow up with a second shot if the first one fails to kill. However, reloads can be rather slow and a maximum of 8 rounds can leave someone vulnerable for a long time. Finding a hiding place is highly recommended, as an empty M590A1 takes the longest out of all the shotguns to reload.
