Billie Adams

Billie Adams was a nano-augmented character in Deus Ex: Invisible War.

History
She was a trainee in the Tarsus program and classmate to Alex Denton, and has known him since they were kids in Chicago.

After the Chicago attack, Billie became a secret agent of the Order and was the first student to learn of Tarsus' true purpose, which was to create a universal biomodification technology, which would be compatibile with every human being.

After escaping the raid on the Seattle Tarsus facility, she was ordered by High Augur Lin-May Chen to investigate a possible cover up over a nanite plague cure in Cairo, where she met Luminon Saman. He recruited her into the Knights Templar, where she developed a zealous hatred for the biomodification. Alex met her again in JC's sanctuary in Antarctica, and had an option to either kill her, knock her unconscious, or escape without confrontation. If left alive, she would appear later on, in the UNATCO HQ on Liberty Island, and would be hostile or friendly depending on Alex's past actions towards the Templars.

Trivia

 * At the Tarsus Acadeny in Seattle, a cigarette pack can be seen in her locker, suggesting that she's a smoker.
