The Assault Rifle is a firearm found only in Condemned 2: Bloodshot. It is carried by members of the Serial Crimes Unit (SCU) and is also found in some weapon lockers. It appears to be a variant of the M4A1 5.56x45mm assault rifle, used by the US military. The rifle is equipped with an aimpoint-style scope for increased accuracy.
The high damage, high accuracy, fully automatic rate of fire, and large ammo capacity make the assault rifle an extremely effective weapon. The weapon is found in the SCU building, Black Lake Lodge, and the Peninsula. There is also an assault rifle available at the start of Trenton District, though it has limited ammunition.
