Perks are stat bonuses which can be activated at certain locations on the map. These locations are usually between point B and a landmark and only become available for activation at the 13:00 timeframe. ISAC will announce the perks becoming active a minute prior.
The perks itself cost 2000 SHD tech to activate, so a good strategy to obtain that is to clear out one of the landmarks to help funding it. After activation, the perk will be active for four minutes before being reset.
