EMP grenade (DX)

The Electromagnetic Pulse (EMP) Grenade is a demolition skill weapon in Deus Ex.

Overview
EMP grenades can either be thrown at a target or planted on walls as a mine. EMP grenades inflicts EMP damage when they explode. The main function of EMP damage is to shut down or disable hostile robots and devices.

Robots
EMP damage can disable a robot by draining the robot's EMP health. Once a robot is reduced to zero EMP HP, it will shut down permanently.

All hostile robots other than the military bot (Page Delta-2 Peacebringer) have an EMP HP of 100 or less. Since explosion mechanics enable explosions to inflict damage at or above the nominal base damage, the EMP grenade's 100 base damage is capable of disabling these smaller robots at the untrained level, as long as the grenade detonates fairly close to the target. The military bot can be disabled by two EMP grenades at the untrained level.

Devices
Turrets, security cameras, alarm panels, and laser tripwire emitters can only be temporarily confused by EMP damage. When confused, security cameras will display a yellow light, and turrets will spin aimlessly. The duration of confusion depends on the amount of EMP damage that is inflicted upon the device. For turrets, security cameras, and alarm panels, the confusion duration ranges from a minimum of 10 seconds to a maximum of 30, where the maximum duration of 30 seconds is achieved by an EMP damage of 165.

Humanoids
EMP damage has no effect on generic humanoid enemies. The MJ12 Commando is entirely unaffected by EMP damage, despite being depicted as using power armor.

Against augmented NPCs with the cloaking ability (Anna Navarre and Walton Simons), EMP damage will cause their cloak to shut down. This is the only effect of EMP damage on augmented NPCs.

The player character (JC Denton) will lose bioelectric energy when hit by EMP damage, subject to the EMP Shield augmentation.

Tips

 * To minimize the risk of detection, grenades may be bounced off walls into another area, or planted on the patrol route of a robot while the robot is away.

Locations

 * During the 1st mission, an EMP grenade is located in the antenna shaft of the communications compound outside of the UNATCO Headquarters.
 * During the 2nd mission, Anna Navarre will provide the player with one or two EMP grenades at Battery Park after the player locates the Ambrosia container. The player will receive either one or two grenades depending on the dialogue choice. If you select the "nerves of steel" comment, you will only receive one grenade.
