- "4 round burst assault rifle. Bursts can be fired in quick succession."
- — Description
Unlike its multiplayer and zombies counterback, the M8A1 is fully automatic in the campaign, and is part of the recomended loadout for "Odysseus", where it is equipped with a hybrid optic, it is also commonly used by all friendly factions, and by the mercs in "Odysseus"
The M8A1 can kill with just three shots at close range, however, at long range, five shots are required to kill.
The iron sights are moderately clear and can be used effectively by experienced players, but to use the M8A1's ranged capabilities, an optical attachment, such as the Reflex Sight or the ACOG Scope is recommended.
Select Fire can turn the M8A1 into a fully automatic assault rifle. Due to its high rate of fire and good damage, it can be effective in close range over the burst-fire, and at longer distances, the player may switch to burst-fire for higher accuracy.
Unfortunately, the M8A1 has no headshot multipliers, so aiming to the head isn't recommended at any range. The M8A1 also suffers from having its three shot kill range ending at 1.25 meters, meaning that at medium range it requires 4 shots in order to kill an enemy.
The M8A1 is available in Green Run, Nuketown Zombies, and Die Rise for 950 points from the Mystery Box. It retains its four-round burst fire mode from multiplayer. Double Tap Root Beer can be very useful with this gun, as its four-round bursts start off somewhat weak, making it difficult to kill zombies quickly. It can be very good for accumulating points in the right hands, and is suitable for shooting zombie hordes.
When Pack-a-Punched via the Pack-a-Punch Machine, it becomes the Micro Aerator. The Micro Aerator can perform exceptional headshot damage, as its four-round bursts can eliminate zombies with ease until as late as round 24, with Double Tap Root Beer. It also holds a large ammo capacity, making it one of the more worthwhile weapons to Pack-a-Punch. Also of note, its hip fire accuracy is increased dramatically, increasing its close quarters effectiveness. It is one of the weapons that is able to be Pack-a-Punched multiple times to cycle through attachments for 2000 points. Attachments include the Reflex Sight, EOTech sight, Target Finder, Millimeter Scanner and the Grenade Launcher.

- The M8A1 is the first weapon in the Call of Duty series to fire four-round bursts.
- When Kryptek: Typhon Camouflage is applied, the M8A1 will act as an overlay, retaining the original colors but adding the scaly pattern over them, whereas with other weapons, the original colors are changed to black. It will also reflect with a red hue when light is shined on it.
- 'HKH M8A1 MK II' is written on the left side of the M8A1. This is easily seen when moving forward while in the prone stance.
- The M8A1 was originally called the XM8 in beta gameplay, and is still called the XM8 in game files.
- The M8A1 naturally fires fully automatic in Single Player, despite it being a natural four-round burst in Multiplayer.
- "5.56x45 MM NATO" can be seen on the magazine.
