EMP disables augs, electronics

She heard the woman coming back at her just as she found what she was
looking for. Anna tore the activator tagstrip from the top of the EMP
grenade and spun, hurling it blindly in the direction of the Tyrant assassin.
She scrambled toward the door and made it to the middle of the
room before the device went off.

With a low, humming snarl, the electromagnetic pulse lit the apartment with
actinic blue lightning. Immediately, the lamps fizzed and went
dark, the television screen dying with them. Anna glanced over her shoulder
as the woman howled and stumbled, crashing to the wooden floor
as her perfectly sculpted cybernetic legs became inert and unresponsive; and
in the same moment Anna felt a spike of migrainelike pain lance
through her head as the pulse struck the delicate electronics in her optical
augmentations. Her vision lost all coherence, dissolving into a wall of
featureless gray static.

The literal blind panic she had felt awakening in the hospital six months ago
returned with punishing force, and Kelso staggered, her hands
sweeping through the air; but then she walled off the pain and the fear, just
like they had taught her in training. The effect of the localized EMP
would last for sixty seconds, perhaps less—she had that long a head start to
escape before the killer came after her.
