Known as SEAL Team's "Weapons Sommelier" Buckshot has thoroughly field-tested and reviewed almost every available military weapon in staggering depth. ST6 relies on Buckshot’s knowledge of lesser-known guns for edge case advantages in ground based operations—but in the interest of time, they strenuously avoid casual conversation on the topic.
Buckshot is a Counter-Terrorist CS:GO agent from the Shattered Web Agents collection introduced on 18th November 2019.
This agent can be randomly given as part of the Exceptional Agent reward when the player earns 52 stars from operation missions in Operation Shattered Web. Alternatively, this agent can be purchased from the Steam Community Market.
