Deus Ex: Human Revolution Stealth and takedowns: alarms, energy and nonlethal routes

Plan a stealth approach around cover, guard awareness and a usable energy reserve.

Edition covered

The 2011 Human Revolution story and core systems, with clearly labeled Director’s Cut PC publisher pictures. Director’s Cut integrates The Missing Link and revises boss arenas; original-edition boss assumptions and energy rules must not be applied blindly to it.

Watch the alert state before advancing

A suspicious guard and an actively hostile guard behave differently. Break sight and wait in a place the patrol cannot immediately inspect before returning to a route.

Stealth tools
ToolUseConstraint
Nonlethal takedownQuiet close incapacitationRequires energy and proximity
Stun gunShort-range nonlethal shotLimited ammunition and range
Tranquilizer rifleDistant nonlethal attackTravel and incapacitation timing matter
CoverHide from direct sightA patrol can approach from the side
VentsAlternate passageMay require finding another entrance

Nonlethal tools still need safe placement

A stun gun, tranquilizer rifle or nonlethal takedown incapacitates a target. Move the body away from a patrol and from environmental hazards, because discovery can change the room’s behavior.

Takedowns consume energy

Do not spend every available unit of energy on an optional guard before a required active-augmentation use. Let recoverable energy return or consume a nutrient when the plan needs more.

Look for access routes before fighting

Vents, alternate doors and movable objects can bypass a defended corridor. An exploration or hacking augmentation may provide a safer route than defeating every guard in the room.

Useful tip

Vents, alternate doors and movable objects can bypass a defended corridor.
