Battlefield: Bad Company
— In game description
The XM8C is a compact assault rifle in Battlefield: Bad Company. Like all SMGs and compact assault rifles in the game, the XM8C is fitted with a suppressor, has a 60-round magazine with 180 rounds in reserve, and the sights cannot be used. Instead, the view is zoomed and the spread is tightened when aiming.
The XM8C can be found as a collectable in the level Crossing Over. It will be located on the roof of a building in the Harbor.
The XM8C is issued to the Specialist kit and costs one unlock point to use. The weapon is preferred by players due to its high rate of fire, decent damage, and effectiveness at longer distances.
Due to its relatively medium range based stats, this weapon can over-power many weapons from a distance, especially shotguns and other Specialist weapons, but can be outdone by these weapons at close range. Another one of its main downsides is that it has a slow, cumbersome reload, much like the XM8, making it advisable to try and deal with any threats before taking cover and reloading. An interesting note about the weapon is that when you walk over an Assault Kit with this weapon, it replenishes your ammo. The XM8C is unlocked at the final level, 25, General of the Army, or included with the Gold Edition.
