The Assault Shotgun could be compared with the Tactical 12-Guage of TS2 and 3. The main difference is this gun is more lethal and reloads much faster than it's counterpart, emptying one cartidge in 3.5 seconds. Like all shotguns, it has no zoom feature, but does allow a sense of accuracy with it's aiming which is also affected by it being one-barelled.

Compared to other shotguns, the Assault Shotgun is very accurate as it's splash kills any opponent from a moderate distance if aimed on target, contrary to other shotguns which are only really effective close-up. Due to this, bots with Assault Shotguns should be approached with caution.
