Z-779 is an old computer with a crudely drawn smiley face on its monitor. According to the lore, it is apparently a person trapped inside the Blacksite's digital mainframe. Has a graphic tablet he really wants to draw on, but has a different job, to mine cryptocurrency.
Z-779 currently serves many purposes, mainly known for assisting with Good People by changing the numbers on the navi-paths doors. Z-779 also causes the Internal Defense System to randomly become active and target players.
