Overshield
From Halopedia, the Halo wiki
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, i.e. 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, but it is slowly reduced in an amount of time. 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 it 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 armor's shields, it provides an additional layer of protection, similar to the effect of an overshield on a Spartan. Towards the end of the campaign, the player (as the Rookie) accompanies a friendly Engineer named Vergil, and staying near to him will grant overshield abilities 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, as their armor lacks 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/green 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.
Tactics
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 game's settings allow an overshield. 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 through meleeing enemies which restores the player's shield, though only in Halo 2's campaign.
- 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.
- In Halo 3 Multiplayer the Overshield only provides one extra shield, compared to the two in the previous games.
- 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 all the Halo games, a charged bolt from a Plasma Pistol will take an overshield down instantly.
- The overshield was most likely inspired by a similar device found in the Marathon series. Using this device in the Marathon Series causes up to two additional layers of heath to be added (yellow/purple).
