As the name indicates, they are shotguns first and foremost. All USGs have their own, separate ammunition and weapon maintenance counters, and some may even accept their own feeding devices.
There are no special restrictions to using a mounted USG, it can simply be selected for use and fired, as if it was a standalone weapon. Critical failures and weapon malfunctions when using the shotgun only affect the shotgun 's Condition, without affecting the mounted firearm.
Attaching a USG to a compatible host firearm may increase the host firearm's weight by one tier. Each USG model has its own compatibility list, see the list below for details.
