Regenerator

Overview
The Regenerator emits a green field of energy which restores a player's shield as well as an enemy's. There is, however, a small delay before beginning the recharge, which means the player is still vulnerable, and you are vulnerable to rocket fire and head shots from a sniper rifle. It also won't help if a lot of people are firing at you. It is the exact opposite of the Power drainer and when it is used in the same area it cancels out the power drainer.
