Power drain

The Power Drainer is a deployable device that has been seen in the leaked internal beta build Halo 3 (Confirmed in Leaked Halo 3 Zanzibar video) and in the recent public "Friends and Family" Beta Test. It has not been confirmed to be in the finalized game. The Power Drainer, like the Bubble Shield and Jump pad, is in the category of "Equipment". It can be deployed using the "X" Button.

The Power Drainer can be activated by deployment.

It can be picked up and deployed on the battlefield.

Only one equipment of each kind can spawn.

A player may only hold one equipment at a time.

Operation
The Power Drainer is like a reverse Bubble Shield; instead of keeping the player inside unharmed, it causes any player's shields within the area of effect to drain away, making them vunerable (instead of the protective Bubble Shield).
