All Vital Suits are powered by Thermal Energy and leave behind a puddle of it when they are destroyed. Piloting a VS uses T-Eng at a constant rate, but using VS features like jumping or hovering reduces it more quickly. If the pilot has less than 100 T-Eng units, the VS will shut down. A Vital Suit's operating condition is separate from the pilot's own health. If a VS is severely damaged, the pilot will have a very brief time to eject before the VS explodes. If the pilot fails to eject or escape the radius of the explosion they will most likely be killed.
