|UAR-42 Ultor Assault Rifle|
|Fire||3 Round burst|
The Assault Rifle main fire mode is three-round burst which is good for medium to long range combat. However, the secondary fire mode is fully-automatic which is excellent for close range encounters, but suffers from somewhat wide spread. The UAR-42 holds 42 5.56mm rounds per magazine, and its reload is pretty fast, so it is viable to do even in the middle of a firefight.
The Assault Rifle is a very balanced weapon overall, a mainstay for the much of the game. However, later on the Assault Rifle becomes less useful after picking up its semi-auto counterpart, the precision rifle. Also, the assault rifle is not very useful against the Mercs, although it can damage them significantly thanks to its high penetration power.
The Assault Rifle is first available after the Barracks section. It is located on a gun rack in a security station. The Assault Rifle is the weapon of choice for Guard Commanders. It is also used by Enviro-Guards.
The Assault Rifle is also available in the multiplayer.
- The UAR-42 features an electronic ammo indicator on its side. This is a reference and/or homage to the 1986 movie, Aliens, where the M41A Pulse Rifle has the same ammo display.
- In the Playstation 2 version of the game, the ammo counter is colored in yellow, while in the PC version it is colored in red.
