The Breacher class is the second unlockable class. The breacher class gives the trooper access to shotguns in the primary slot while retaining all other equipment slots. With this class doors can be breached using the primary weapon and done faster than picking the lock or using the dynamic hammer.
The weapons available to the breacher class are a number of different shotguns both pump action and semi automatic. Shotguns have spread not unlike real life and can eliminate nearly all enemies in little more than a single shot. There are a few shotguns included that are magazine fed rather than tube fed.
