Purity First

Purity First is a radical anti-augmentation group in Deus Ex: Human Revolution.

History
In 2027, Anna Kelso recalls that the group is responsible for several assaults and murders across the United States. They have similar intentions to the less extreme group, Humanity Front, though they accomplish their goals through violence, not (more or less) peacefully protesting.

Early in Human Revolution, they take over a Sarif Industries processing and assembly plant in Milwaukee Junction, where the prototype Typhoon Explosive System was being prepared for manufacturing. Adam Jensen is sent in to resolve the situation, and evetually finds Zeke Sanders, the group's leader. How the situation is resolved is up to the player.
