Glitches

Some sections or situations are affected by technical errors in the Deus Ex series. While uncommon in their occurrence, they exist nonetheless and can cause issues for the player.

Deus Ex Glitches
Glitched Brooklyn Naval Shipyard Conversation

This is a glitch that occurs with the friendly soldiers outside of the Brooklyn Naval Shipyard (if the player had spoken to Vinny prior to make them friendly). It is unknown what causes this glitch, but it crashes the player's game when they speak to the soldier who acknowledges who JC is. Avoiding that particular soldier or skipping through the conversation will generally stop it from occurring.

Deus Ex: Invisible War Glitches
Non-stacking Multitool

Some Multitools in DX2 will not stack with the player's collection of Multitools.

Deus Ex: Human Revolution Glitches
Ventriloquist Sarif

This is a glitch that occurs during the "conversation fight" with David Sarif after the Highland Park level. There is a chance where Sarif's facial animations do not play, causing his voice files to play but with no facial animation. It is unclear what causes this glitch, though it can be rather humorous.

Knocking Out Jaron Namir

This is a glitch that can be used to the player's advantage in the Jaron Namir boss fight. With correct timing when Namir climbs over a wall during the fight, the player can activate a non-lethal takedown, defeating Namir instantly.

Glitched Textures

This is a graphical glitch that may occur where the textures for the environment and character models (minus the head for some reason) appear to be covered in a grainy, glitched texture.

Talon A.D. Mission Bug

This is a glitch that is present in the Talon A. D. quest where the mission does not update after finding information within the butcher shop. Note that is glitch is always present and is not random.

Body Drag Death Glitch

This is a glitch that may occur if the player moves an unconscious enemy after them being in one place for a long time. If the player tries to drag them, they will be rendered dead after rag-dolling for a moment. It is unclear if this affects the Pacifist Achievement.
