How to Play
This MX9 loadout works better when fighting enemies at close to mid-range in battle. Double Time, Battle Rage, and Quick Fix will help survive those encounters and dominate enemies on the field.
To make MX9 more effective at mid-range, consider equipping attachments that increase recoil control and aiming stability, like in our recommended attachment setup. You can also add an optic with a Red Dot Sight to be more precise when aiming.
Players going with this loadout and attachment setup should bring it on medium-sized maps and game modes like Team Deathmatch or Hardpoint. It is to avoid getting stuck at multiple gun fights, as MX9 lacks the magazine size to fight numerous enemies at once. However, it’s hard to see it lose at a 1v1 shootout with this loadout.
