Energy

Being machines, both the heavy machinery used in Mechanical Augmentation and the Nanites used in Nano Augmentation require a power source to function. Bioenergy is the power used to operate these devices. In Deus Ex and Deus Ex: Invisible War, the player has a limited reserve of Bioenergy, and both using Augmentations and being hit by EMP Weapons will drain this meter. When the meter is empty, the player cannot use augmentations. Bioenergy can only be replenished through the use of Power cells, but the Power Recirculator aug can conserve the amount of energy used.
