Regenerator

The Regenerator is a piece of equipment.

Background
The Regenerator, like the Bubble Shield, emits a small, green field of energy which restores a player's shield as well as an enemy's for 15 Seconds. There is, however, a small delay before beginning the recharge, which means the player is still vulnerable, and you are vulnerable to weapons which can kill the player in one shot. It also is less effective if a lot of enemies are firing at you. It is the exact opposite of the Power Drain and when it is used in the same area as a Power Drain, the Power Drain overpowers the Regenerator. Other ways in which the Regenerator is dissimilar from the Power Drain is that the Regenerator remains rooted in the same spot where it is deployed while the Power Drain can move.
