The XM8A1 is a Rifle in Strike Force Heroes 3, used by the Medic and Engineer classes.


XM8A1 appear as a short assault rifle which have an extra handle at the top. It have green-grey theme, and some of the part are painted in black. It have a middle and a front sight, along with the cylinder tube and a small portion of the barrel poking out of the hull.


The XM8A1 could be seen as a full auto, low powered sniper rifle. It has the above average damage and accuracy for a Rifle, but its main drawback being its low RoF. The unique gold, custom version is the Harbinger.


Best used by players looking for a balanced weapon. Excels most at mid-to-long range due to rather high accuracy and damage. Generally, it does not perform very well in close range battles, so use Blades (Big Willy, Sky9 Iron, and Hattori Hanzo are best) to get up close without getting killed easily.


  • Successor to the XM8 in SFH2. Based on the real life XM8, which was rejected as a replacement to the M4/M16 series of rifles in the U.S Military.
  • It's appearance is based on the M8A1 from Call of Duty: Black Ops II, albeit darker.
