ADVENT Security Tower (XCOM2)
ADVENT Security Towers act as watchpoints in all ADVENT cities.
Interaction with XCOM
ADVENT Security Towers produce detection radii, and can reveal concealed XCOM operatives if they step into their detection radius.
Specialists can remotely hack these towers with their GREMLINs to obtain different combat bonuses such as concealment, immunity to enemy attacks, and a variety of other skills, or 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.
