Portable gravity lift
From Halopedia, the Halo wiki
The Portable Gravity Lift is a piece of Covenant deployable field equipment. It is a new feature for Halo 3.
Operation
The Portable Gravity Lift must be picked up. Afterwards, it may be deployed by pressing the "X" button. Once deployed, the Portable Gravity Lift unfolds and projects a bluish-purple gravity beam that propels the player into the air - exactly the same as the Covenant's larger version, the unmodified Gravity Lift, but on a smaller scale. When placed near a wall, a player can use this device to jump over it. Doorways can also be blocked with it. It has the power to lift vehicles, such as the Mongoose, and other objects besides players into the air.
Also, players of the Halo 3 Beta used tactics like deploying the gravity lift and launching the Power Drainer up to the enemy.
It is activated by the X-Button now dubbed the "Equipment Button", by Frankie.
Appearances
The Portable Grav Lift was seen in the H3 ViDoc while a group of players were attacking High Ground. To the untrained eye one would suppose that a player just grenade jumped, but there was a pad on the floor that was radiating a blue light similar to the Man Cannon. It is another piece of equipment similar to the Bubble Shield, Power Drainer, Trip Mine, and Radar Jammer.
The Portable Gravity Lift was confirmed on Bungie.net.
