Drop shield/Gameplay

Campaign and Firefight

 * The Drop shield is available on the levels Winter Contingency, ONI: Sword Base, Nightfall, Tip of the Spear, Long Night of Solace, New Alexandria, The Package, The Pillar of Autumn, and Lone Wolf.

Multiplayer

 * The Drop shield is more useful for players playing as Spartans rather than Sangheili, as a Sangheili's health already regenerates.
 * In Invasion, players on the defending team should use the Drop shield to protect the core if the core has been taken outside its spawning point.
