 * Inside a box shortly after exiting an elevator in the Sarif Industries Milwaukee labs.
 * The LIMB Clinic in Detroit (two can be bought for 5000 credits each, restocked on second visit to this hub). Also one from sidequest from doctor on second visit to detroit.
 * Detroit Downtown Apartments, third floor of the westmost building, inside an illegal augmentation 'chopshop' with a level 5 security door (code to get in: 2356), then hack the level 2 terminal, then hack the level 1 computer for the final code into the area with the kit).
 * 2011-08-27_13.14.44.jpg the Derelict Row sewers in a hidden area accessible by breaking through a wall. Location of wall is shown by Jensen icon in the image.
 * One in Isaias Sandoval's apartment across the street from Adam's place. It is connected to 2 EMP mines hidden under the body that should be disconnected before grabbing the kit. Be careful, it's bait. (only appears when the primary quest sends you here.)
