Holo-drone

Holo-drones are small, spherical objects capable of hovering and flying, that create holographic fields. Holo-drones are used for the Covenant in serveral varying ways. They can be used as communication devices or even as holographic decoys of individuals who use them.

Sesa 'Refumee, the Elite leader of the Heretics, used Holo-Drones as decoys of himself when the Arbiter attacked the Heretics' Base.

They are very weak in battle, and a direct shot will destabilize them, and cause them to shimmer (Giving away their Hologram origins). Holo-drones are similar in appearance to Plasma Grenades before being deployed; only they are a little bigger and they can hover.
