Václav Koller (pronounced [ˈvaːtslaf]) is an underground augmentation specialist based in Prague, Czech Republic. He owns a book shop named The Time Machine in Prague, and his clinic is in an underground area below the shop, accessed through a secret bookshelf door.

Koller acts as Adam Jensen's personal neuroplastic surgeon during his stay in Prague.


Koller deals with both standard and controversial augmentations. He is an eccentric engineer who has used his skills to augment himself extensively.[1]

He has associations with many of the factions in Prague, including organized crime. In particular, he is under the protection of the Dvali crime family for an unknown reason.[1]

If Adam undertakes a side mission from Otar Botkoveli during his assignment at Golem City, Adam learns that Koller's "deal" with Radich Nikoladze is that he serves as the crime leader's physician, providing maintenance for Nikoladze's augmented leg.


  • After Jensen returns from G.A.R.M., Koller may be found dead on the chair is his clinic with a monitor that says "He had a deal" on his lap.
    • This happens if Jensen had entered into an agreement with Otar Botkoveli, but failed or neglected to complete the two favors for him, Otar will not be granted the firm footing he needed to overthrow Radich, prompting him to murder Koller to cut off Nikoladze's Neuropozyne supply in order to weaken him.
      • If this is the case, Jensen will receive a call from Otar shortly beforehand with a tortured and barely alive Koller calling for him in the background.
    • Alternatively, if Jensen does complete the two favors and does not kill Gallois, then it is Nikoladze himself who will order the hit on Koller since as Gallois was Radich's Neuropozyne courier, removing him from the picture means that the deal is broken.
    • One way to save Koller properly is to either kill both Otar and his henchman Vano, therefore forfeiting several side quests and Achievements (one of them being Pacifist), or complete both favors for Otar then murder Gallois when given the opportunity. Once Otar has usurped Nikoladze he will have the latter killed but sparing Koller in return for the favors he now owe Jensen. 
    • For an Otar-alliance pacifist run, doing both favors will spare Koller. For good measure, make sure to do Gallois's side mission to negate the possibility of Radich killing Koller.
      • Reports on this have been mixed, though. Probably due to an unaddressed bug, some have reported doing both missions, with Gallois going into hiding, and being personally praised by Otar, and Koller still end up being murdered.


  • Jensen pronounces Koller's first name with a soft "c" instead of the proper "ts". Even Koller himself pronounces it this way about half way into the story, when he hails Jensen over to fully calibrate his system to be compatible with his experimental augmentations.
