- “The Mobile Pack-a-Punch System was originally designed and constructed by the Coil Arms Division as a mean for providing more firepower for their troops in the heat of battle. Following the raid of both the Coil Arms Division's headquarters and the mine on Fidea VI, the Eclipse Medical and Health Services managed to recover the schematics for the device and managed to reconstruct it for the troops of the Galactic Council of Alliances.”

The Mobile Pack-a-Punch System is a special unlockable utility found in Call of Duty: Eclipse Warfare and Call of Duty: Eclipse Warfare III. It is unlocked once the player has completed all of the easter eggs in the Zombies maps leading up to Siege of Remnant. When the player completes both Siege of Remnant and all of the previous easter eggs, the Mobile Pack-a-Punch System can be used on all previous maps, including all of the Extinction maps. In Call of Duty: Eclipse Warfare III, the Mobile Pack-a-Punch System is automatically given to plays who have purchased the Zombiology Collection, allowing it to be used on all Zombies and Extinction maps like before.
To use the device, the player must have at least 5,000 points ready. When they do, they can press right on the D-Pad, which will cause the weapon to be quickly scanned once in a red light and then quickly scanned again with a green light, applying the map's Pack-a-Punch camouflage on the weapon to signify the upgrade.
