"The military version of a gadget which builds muscle through bursts of electrical stimulation. It relieves tiredness and restores your action points, but causes massive trauma (even causing death in agonising pain)"
Can be used by an uninjured citizen to recharge AP (5 AP) in addition to drugs, food and water. However, the citizen is immediately injured and can not gain more than 5 AP from regular AP sources. The EMS System is then uncharged, and with a new Battery can be used again.
(Note: The EMS system cannot be used by someone that is already injured, whether by zombie or by previous use of the EMS system.)
