XCOM 2/Facilities

"There's room for us to expand our facilities onboard the Avenger, Commander, but we'll need more engineers to clear out space for construction first." ~Chief Engineer Lily Shen

The build facilities menu in the Avenger.

Facilities provide XCOM with a myriad of new capabilities. Some facilities train your units, some speed up your research, some produce items, and some just provide the electrical power used to fuel your other facilities. Constructing and maintaining facilities is a key part of developing your own forces and staying ahead of the ever-growing alien threat.

All facilities require upkeep in the form of supplies. Whenever you would receive a supply drop from the resistance, each facility's upkeep cost will be subtracted from the amount of supplies found in the supply drop. The upkeep cost is not something that needs to be "paid", facilities will always continue to function at full capacity as long as they exist.

Clearing room for facilities

When the game begins, the Avenger's rooms are filled with junk that blocks construction of your facilities. If you enabled the tutorial, every room will be blocked. If you did not enable the tutorial, only one room will be empty and available for construction.

Rooms may be blocked by one of three types of debris:

Debris	Engineers staffable for clearing	Notes
Alien Debris	1	Appears in all four rows. Gives supplies when cleared.
Alien Machinery	2	Only appears in the bottom 3 rows. Gives supplies and alloys when cleared
Exposed Power Coil	3	Only appears in the bottom 2 rows. There are always exactly two exposed power coils. Gives elerium when cleared. On Legend difficulty, additionally gives alloys when cleared. Facilities built on an exposed power coil do not consume power. Power Relays built on an exposed power coil provide an additional 5 power.

If playing on Legend difficulty, an additional engineer may be staffed onto Alien Debris and Alien Machinery rooms at or below the 3rd row.

Power

Most facilities require power in order to operate. In vanilla, the Avenger has 12 power by default, but 6 of it is already occupied by core facilities, leaving 6 power open for initial construction. In War of the Chosen, the Avenger's default power capacity has been raised to 15. With the 6 power occupied by essential systems, this leaves 9 power open for initial construction.

Additional power capacity can be earned through constructing power relays. Power relays may also be constructed and staffed in order to give additional power. Power relays placed on an exposed power coil provide an additional 5 power. Power capacity can also be expanded through rumors or, in War of the Chosen, covert operations.

If there is insufficient power capacity for a facility's construction or upgrade, it will be impossible to initiate the construction or the upgrade until the power capacity has been expanded to meet the facility's needs.

Facilities constructed on an exposed power coil do not require power to construct, to operate, or to upgrade. Power Relays constructed on exposed power coils provide an additional 7 power.
