Z-90 Photonic Coalescence Emitter/Aegis

The Z-90 Photonic Coalescence Emitter/Aegis or simply the Hardlight Shield is an armor ability featured in Halo 4. Using Forerunner hard light technology, it is a photon emitter that can fuse particles of light into a rigid, dissipative barrier used in a similar manner to a riot shield. When used by a Spartan-IV, it forms a full-size aegis-class, anti-personnel defensive shield in front of the user.

Trivia

 * This shield only protects from the front; the sides and back are unprotected.
 * Movement speed is slowed and normal shields do not recharge when the Hardlight Shield is deployed.
 * It can be projected by watchers to protect knights or a smaller version for a crawler's head.
 * It can be seen as the Halo 4 similar to Halo: Reach's Armor Lock.
 * While the Hardlight Shield does not protect against vehicular contact, it does have the ability to deflect Scorpion rounds.
 * The Hardlight shield will reflect shots from a Scattershot. If used at point-blank range, the scattershot round may even ricochet back to the offending Spartan, disintegrating them instantly which counts as a kill.
 * Unlike Armor Lock, the Hardlight Shield does NOT offer protection from vehicle splatters. If a Ghost or Warthog is charging torwards you, do not activate the Hardlight Shield.
 * Contrary to popular belief, the Hardlight Shield does not lose energy when it takes damage. The color change only shows how much longer the shield can be used for, not how much damage it can sustain. The shield only shuts down when the few precious seconds it can be used for pass, or if the player using the ability releases the Armour Ability button on their controller. If attacking a player using a Hardlight shield, do not waste ammo shooting the shield itself.
