The Planetside 2 PC servers will be coming down at 6am (Pacific) / 13:00 (UTC) for a brief hotfix. Estimated downtime is 1.5 hours.
The following changes are included:
In addition to damaging them, HIVE Shields can now be overloaded by enemy infantry close enough to interact with the terminal; defending players can interact with an overloading HIVE to disable the overload.
Along with a new visual effect, overloading HIVEs will broadcast a warning to all players within 150 meters when the shield is being overloaded or taking damage.
