Overshield

Overshields are a form of Covenant developed technology that strengthens the Energy Shields of the user.

Function
The Overshield technology was developed by the Covenant to enhance their Elite warriors' shields. In Halo: Combat Evolved and Halo 2, overshields boost a player's shields to 300%. In Halo 3, however, these overshields only boost a player's shields to 200% (although, MLG's playlists have a Custom Powerup Overshield that is of 300% strength). Overshields can be used by any Spartan (in Mark V or VI MJOLNIR armor) or Elite who might come upon it.

It takes approximately three seconds to charge once picked up. During this time, the player is invincible. The player's normal shield does not take damage until the overshield is completely depleted (although any damage overlapping from something destroying the overshield, for example a grenade's explosion, will also do damage to the player's normal shield). If the overshield is picked up when the player's shield is below 100%, the player receives a full charge and the effects of the overshield stay.

In the single player Campaign the overshield is reduced only when the player takes damage. In Multiplayer, it gradually depletes over time. The overshield can only be found in Campaign in some levels of Halo: Combat Evolved. Halo 3 includes a piece of equipment in Campaign, invincibility, which has a shield-strengthening effect, though only lasts 10 seconds. In Halo 3: ODST, all hostiles next to a Covenant Engineer are given an overshield; in the case of Brutes, this does not enhance their armour's shields, it stacks on top of it. Towards the end of the campaign, the player (as the Rookie) accompanies a friendly Engineer named Vergil, and staying near to him will grant overshields as well, though it isn't quite clear how it effects the player, as the HUD for Orbital Drop Shock Troopers does not include a shield meter, their armour not having shields.

Appearance
In Halo: Combat Evolved, the overshield is a glowing red orb of energy encased in a clear glass cube. In Halo 2, both the orb and cube are gold in color. In Halo 3, the orb, again glowing red, appears to be held together by several small magnets. After walking over an overshield in Halo: Combat Evolved or Halo 2, the person's HUD shield display changes color from blue to red then green. In Halo 3, the HUD shield display color changes from blue to green. Each color indicates one layer of shields.

While wearing an overshield in Halo 2 and Halo 3, the MJOLNIR armor is surrounded by a glowing force field which is easily seen even when wearing the Active Camouflage. This does not happen in Halo: Combat Evolved.

On the HUD, the shield monitor shows a light green for a fully charged overshield, red for the second level, and the usual blue/purple (depending on player model) for the normal shields. The Halo: Combat Evolved overshield shows yellow at the highest level, rather than green. In Halo 3, the overshield only raises your shield level by one level, showing green as fully charged.

Advantages
Overshields effectively triple the strength of the MJOLNIR and Elite armor's shields in Halo 2 and double in Halo 3. The shields can now protect the person from heavy weapons such as Rocket Launchers, Fuel Rod Cannons, Sniper Rifles, Fragmentation Grenades, and even Plasma Grenades. Also, while the shields are charging, you are immune to conventional damage, but will still be vulnerable to assassination, Guardians, and falling to your death.

Disadvantages
Due to the bright glow of the overshields, the wearer is made more visible to other players, often drawing unwanted attention. In Multiplayer, the overshield slowly loses its strength over prolonged periods of time, unless the player is a Juggernaut, VIP, or Grifball carrier. An overshield can be fully depleted by an overcharged Plasma Pistol shot. Also, many players place traps near/on the Overshield, such as throwing Fragmentation Grenades or placing Trip Mines near it.

Note: The glow does not appear in Halo: Combat Evolved, and therefore has no disadvantages. The glow was probably added in the later games to balance the powerup.

If, in Halo 2 and Halo 3, Overshields and Active Camo are used both at the same time, it renders the Active Camo useless due to the glow that the Overshields give off, making the player visible.

Trivia

 * The Black Eye Skull allows the player to achieve overshields without picking up the item, though only in Halo 2's campaign.
 * In Halo 2, the Arbiter's overshield is blue.
 * In Halo 3, you can pick up the overshield (or Active Camo) as equipment if you have a piece of equipment and hold your equipment change button (default RB) and barely touch the overshield. Then if you die you drop the Overshield, or if you pick up another piece of equipment you will drop/pickup the overshield, allowing you to surprise your enemies, this works on matchmaking online.
 * The only game in which the Overshield appears in the Campaign portion of the game is Halo: Combat Evolved.
 * The first overshield is seen in the Pillar of Autumn, in the Covenant boarding ship. Other levels with the overshield in Halo: Combat Evolved are Truth and Reconciliation, the Silent Cartographer, Assault on the Control Room 343 Guilty Spark, the Library, Two Betrayals, Keyes ,and The Maw.
 * In Halo 3 Multiplayer the Overshield only provides one extra shield, compared to the two in the previous games.
 * The Meta, from Red Vs. Blue: Reconstruction, appears to have both Active Camouflage and an overshield.
 * In Halo: Combat Evolved, when you walk over an overshield, your screen will turn pink for a second and you will hear the same sound as when your shields are loading.
 * In Halo 2 and 3, when you have an overshield, one slice with an Energy Sword will not kill you. It will probably take about two hits.
 * In Halo 3, the overshield charges much more slowly than before.
 * On the Pillar of Autumn (Level), the overshields that are in the Covenant boarding craft are sometimes blue. This may only occur because the interior of the boarding crafts have a blue lighting.
 * In Halo 3, overshields will deflect bullets and grenades.
 * In all the Halo games, a charged bolt from a plasma pistol will take an overshield down instantly.
 * In Halo 3, if in Forge you set the runtime minimum of the Overshield to the same as the runtime maximum, and change the respawn time to ten, the Overshield never disappears. This means that you could stand on the overshield, and it would keep respawning over and over again. This makes you invincible to any attack, except assassination.
