VATS Matrix Overlay (Fallout 4)

VATS matrix overlay is a mod available for power armor helmets. It requires Science! rank 2 to construct.

Effect
The upgrade description reads "Increases VATS hit chance." It increases VATS hit chance by roughly 9-10%. (Tested on a stationary turret over multiple distances, compared against without the upgrade).

Alternative upgrades
The 'sensor array' upgrade "increases perception" by 2 points. This results in a very similar VATS hit chance when compared to the VATS matrix overlay (only 1-2% less chance at the same distance). This upgrade requires the Science! rank 3 perk to construct. The potential benefit of using sensor array compared to VATS matrix overlay is the carry-over to stealing and lockpicking attempts, and any other benefits of an increased perception stat. (Tested on a stationary turret over multiple distances, comparing VATS hit chance with VATS matrix overlay and sensor array).
 * Perception also determines the distance at which enemies appear as red blips on your HUD.

Locations

 * Can be crafted at Power armor stations
