XCOM 2

A rumor is a point of interest on the Geoscape that you can scan with the Avenger to obtain a reward, such as Intel, supplies, new missions or recruits. These occasionally appear after completing a mission but only remain on the map for a few days or until a new rumor of the same type appears. If you select a rumor, you can see the reward and the number of days it will take to investigate. Rumors are fairly common in the game (and there's usually no reason to pass up goodies) so this trophy should come naturally.
