Phoenix Logs/Forerunner/Controller Sentinel


 * Forerunner system offensive/defensive drones


 * The Controller Sentinels’ primary function is to guard valuable Forerunner
 * technologies on the Ark. Developed and deployed to counter the escalating
 * threat from the UNSC and the Banished, these flying Sentinels are loosely
 * 'tethered' within set radii of important sites and will attack anyone that comes
 * close, or attempts to take control of the sector.


 * An impenetrable energy shield protects the front of each Controller Sentinel, an
 * improvement on the already powerful shields used by the Enforcer Sentinels
 * whose function was to suppress Flood outbreaks. Underneath it fires a
 * continuous Sentinel Beam to prevent enemies from hiding in its blind spot, but
 * its primary weapon is a devastating supercharged Sentinel Pulse.
