At closer ranges, this mode usually a better choice for direct attacks since it knocks weaker enemies off their feet, can be fired quickly before you retreat behind cover, and can't be blocked by a charging Skaarj's arm blades (although it can be dodged). It is very useful in corridors or other places with less space. This mode is useful in close and medium ranges and some times even in long range. Compared to the primary fire, the secondary fire is two times slower, but each used round does 4 more damage, therefore it uses a lot less ammo than the primary fire and deals more damage. Secondary Fire Produces a slow-moving energy projectile that breaks apart on impact, releasing five shards bouncing off surfaces. As the rate of fire is 10 rounds per second, the primary fire eats ammo very rapidly. Primary Fire Fires bullets at a machine gun-like speed, killing most adversaries fairly quickly. It appears to cycle the rounds through some sort of rotating cylinder that can be seen on the side of the weapon, and, upon triggering the alternate fire, all five shards loaded in the cylinder would be shot without being detonated somehow. He does mention they are caseless, but 'build up a nasty dust', from where the nickname 'Duster' comes. Isaak describes the rounds themselves as 'depleted uranium shards', although he does not specify how they function. It feeds off box magazines in bullpup configuration, each containing 75 rounds. It is very useful at close range and to bounce shots around corners. The M32's primary fire mode is an automatic stream of bullets, useful at medium to long ranges, and the alternate fire mode shoots a cluster of uranium shards that detonate on impact and ricochet in a flak pattern. You receive this weapon from the start of the game and it may be the most versatile weapon you encounter.

The M32 Combat Assault Rifle (CAR), dubbed 'duster' by marines, is the standard issue assault rifle of the various terran forces (including the marines and the colonial authority). 1.1 Unreal Mission Pack: Return to Na Pali.
