ADVENT Security Tower (XCOM2)
ADVENT Security Towers act as watchpoints in all advent cities, they are able to reveal your troopers if you step in their sight radius. These towers can be remote hacked to obtain different combat bonuses such as concealment, immunity to enemy attacks, and a variety of other skills, and on occasion various resources. If you successfully hack a tower you will obtain the bonus and disable the sight radius, but if you fail then you get the negative outcome for the hack. A failed hack will also break concealment.
