L7-92 is a synth working for the Institute in 2287.
Background
G6-43 was assigned to work group G1672 alongside fellow synths G6-43, M9-11, W4-40, and Q2-87. They were sent to conduct unspecified operations at a surface location identified as "Site Delta." A note from Max Loken indicates that they are not finding as much material as wanted from the site, which may lead him to shut down the site in the near future.[1]
Notes
The synth Brooks in the Far Harbor add-on also has the synth designation L7-92.
Appearances
L7-92 is mentioned only in Fallout 4.
