Introducing Operation Shattered Web. For the first time in CS:GO, bring your favorite character into battle with all-new equippable agents.
You can unlock all-new T and CT-sided characters equippable on any map. All-new CT Operators and T Agents are available as mission progress rewards. Complete missions and earn Stars to unlock them and equip them for deployment. Or equip the default Local Agent or Operator to use the pre-existing map-based characters.
