Arachnos Dig Site
Overview
The Arachnos Dig Site is a subterranean neighborhood in the Hero City Zone Faultline. It does not appear on the zone map and can be difficult to find and navigate.
Underneath the western portion of the zone lie a series of tunnels created by Arachnos. Several missions from Agent G send you into the tunnels, and they contain mission doors which can be used for Radio Missions. Many players have difficulty finding the tunnels, as the entrances are not obvious, and some of the mission doors are even beyond the normal map boundary, leading players to believe their mission is bugged and placed outside the zone.
There are two entrances to the Arachnos Tunnels, one north of the dam, and one south of it.
- The northern entrance is next to a dead tree at the top of Lift H in the Overflow neighborhood.
- The southern entrance is under an Arachnos complex just south of the dam in the Overbrook Dam neighborhood. Turn right (West) as you exit the power plant on the South side of the dam. You'll see a small bridge that leads to an Arachnos Flier landing pad. Drop down under the bridge and turn right (facing the dam). You'll see the tunnel leading downward directly ahead of you.
Both the entrances, and the tunnels themselves, are available on the Vidiotmaps map patch.
