Compared to other Bruiser-type units, he has the weakest damage output. However because of his unique ability after capturing Mobile Hardpoints, he will restore his health and make use of his limited speed boost to reach the next Hardpoint.
The Stim Bruiser uses an EVA-8 Shotgun instead of an automatic weapon like most pilots. Because the shotgun has a very wide spread, the Stim Bruiser usually distances himself further away from enemies. This can be a plus as the spread of his shotgun is so wide it can damage an entire squad of Grunts at the same time.
