Defibrillator

The Defibrillator is an item used only in Left 4 Dead 2. It can be used to revive dead teammates. The defibrillator replaces the health kit and is a one time use item. Its symbol is a lightning bolt.

To use the defibrillator, players must walk up to a corpse, which will acquire a faint red glow, and press mouse1 / right trigger. A charging meter, which takes a few seconds to complete, is shown. Then, there is a short burst of electricity and the teammate has been successfully revived. He/she comes back at 50 health and can pick up all dropped items before continuing.
