Pieter Burke is the primary antagonist of The Missing Link DLC for Deus Ex: Human Revolution. He is the commander of the Rifleman Bank Station detention center, and the Director of Special Operations at Belltower.
Burke is a former U.S. Marine Corps Force Recon officer who was dishonorably discharged. He is described as charismatic and a natural leader, but he also has sexist tendencies. The specifics of his service record are almost entirely classified. Burke maintains a close acquaintance with Belltower's high echelon and the Tyrants.
After discovering the stowaway Adam Jensen aboard the Hei Zhen Zhu cargo ship, Pieter left Netanya Keitner, the offshore base commander, with interrogating Jensen. It was revealed later that she assisted him in escaping, due to her role as an Interpol double agent. After docking at the Rifleman Bank Station, Burke proceeded to relay instructions to his top scientists, and unlocked a hidden elevator, unaware of Jensen's presence.
After having his spare augmentations stolen and discovering Keitner's defection from Belltower, Burke placed the facility on alert and began filling the prison cells and labs with toxic gas in an attempt to kill all potential witnesses. After Jensen made his way through all of his forces, Pieter then made a last stand against Adam in a hangar containing a 80-X Boxguard and several Belltower guards.
Regardless of whether Jensen killed or spared Burke, his subordinates are promptly forced into retreating by Garvin Quinn impersonating him. It is likely that Burke was killed even if Jensen spared him, as a conversation log found on Garvin Quinn's hidden computer shows he has direct orders to take Burke out, suggesting that his death most likely occurred anyway.
- Pieter notably wields a custom designed revolver obtainable by neutralizing him or by accessing a hidden safe in his office (behind a painting on the wall, opened by a button under his desk). If taken from his office, Pieter will wield a Machine Pistol in place of his revolver during the confrontation with him.
- The unique revolver is 'fully upgraded'; despite being slightly less powerful than a regular fully upgraded revolver, and without explosive rounds or the ability to upgrade it further, it's still effective for the short time-span.
- While taking out bosses lethally does not count against Pacifist, killing Burke in the Director's Cut version of the game denies the player the achievement, as he is counted as a standard enemy soldier by the game. DO NOT utilize lethal arms if you wish to earn this achievement.
