XCOM 2

For this trophy, you need to build a facility on any of the available slots on the Avenger and then upgrade it. Not all facilities can be upgraded. You will know one can if there is a purple arrow in the lower left corner of the facility. Simply highlight a facility and press to see what upgrade options are available. Unlike facility construction, which takes time (dependent on the total number of Engineers you have), upgrades are instantaneous. A good choice to upgrade is a Power Relay, as you will need additional power later in the game to run all of your facilities.
