GMS compound is the first major dungeon the player visits during Underrail storyline. It is located in Lower Underrail, and can be accessed via the Lower Underrail exit from South Gate Station, by heading north from the station platform on SGS level 1.
The player travels there during Gorsky's task and is tasked with finding a way to open the sealed door on the first level of GMS compound.
Level 1: Offices
The initial level, some dusty old offices full of rathounds and junk. A large sealed door is located near the entrance. To the west is an unpowered elevator, to the northwest are stairs and the power generator for the whole compound is also on this level.
An Omni-Tool can usually be found somewhere on the first level, and it proves useful as the whole compound proper is full of accessible ventilation shafts. Just remember that rathounds are more than capable of crawling inside the same ventilation tunnels.
During your mission here, Gorsky's team will be waiting near the entrance.
- A room in the southwest part of the area has a door requiring 25 Hacking.
- The room can also be entered through the ventilation shafts
- It contains a backpack with an Omega ID Card oddity, 1 XP
- The backpack also contains a Key (GMS)
- It also has hidden safe (detected with 7 Perception), which can be opened with 30 Lockpicking
- In the southeast corner is a Power Generator. It can be configured to bring power back to the elevator
- In the southeast part of the area, there's a room with a footlocker that requires 25 Lockpicking or can be opened with the Key (GMS)
