The XSSG is the T3 light tactical gun of the Kommander class. It is an automatic shotgun sporting high close-range damage along with decent effectiveness at mid range and a fairly fast reload. Like all shotguns, effectiveness at long ranges will drop substantially due to the shot spread.

While the XSSG has the appearance of a pump-action shotgun, it functions as an automatic shotgun capable of firing 10 rounds in succession and reloading a full 10 rounds at once (rather than having to reload round-by-round).
Originally, the XSSG had a semi-automatic fire mode. However, it was changed to fully automatic in a subsequent patch.
