Overshield

Summary
The overshield technology is used by the Covenant to enhance their Elite warrior's shields by a factor of three. It can be used by any Spartans that might come upon it. During multiplayer it is temporary and gradually deteriorates.

It looks simply like a ball of energy encased in a glass cube. Once the user breaks the glass container, the energy dumps directly into the nearest energy field and increases it for a limited time. This theory hasn't been proven, because hardly any Covenant technology has been recovered intact by UNSC forces.

While present in both Halo 1's campaign and multiplayer, in Halo 2 it can only be found in multiplayer.

After walking over an overshield powerup, Master Chief's shield is raised from blue to red then green. In Halo 1's campaign, the overshield will not go down unless fired upon. You cannot pick up another overshield while still wearing one, no matter how low it is.

When wearing an overshield in Halo 2's multiplayer, the MJOLNIR armor is surrounded by a glowing force field, which is easily seen even if you are also wearing the Active Camouflage.
