Overshield
From MLGWiki
The overshield is a powerup which gives the player several extra bars of temporary shield. The overshield will slowly decay after being activated.
While the overshield is charging, the player is invincible.
The Overshield has different properties in each of the Halo games.
[edit] Halo: CE Overshield
The Halo: CE Overshield is a glowing red orb housed inside a cube casing. When a player picks up the Overshield, he or she receives three times the shielding power of a normal player. When hit by opposing fire, the player's normal shields will not take damage. The Overshield slowly drains with time in multiplayer action, as well as reducing the amount of extra shielding left when an opponent successfully fires upon the player.
[edit] Halo 2 Overshield
The Halo 2 Overshield is a glowing yellow orb inside a cube casing. The Overshield provides two extra levels of shields to the player: green and red. Draining the Overshield is typically very difficult, however a Plasma Pistol may do so with a single overcharge bolt. The Overshield enables a player to venture into areas typically thought as strategically unsound. It is typically thought of as the most powerful power-up as it yields more time, and strategical options, to a player.
