The latest CS:GO Broken Fang operation brought many new things. Among them, there are some new agents. Complete the missions, collect stars and exchange them for agents. All Distinguished Agents will cost you 5 stars, Exceptional Agents 7 stars, Superior Agents 10 stars and Master Agents 25 Stars. On the other hand, if you don't feel like completing missions you can always purchase those agents on the Steam Marketplace.
