Reviving allows a player to get another player out of the hospital, no matter how long they are in the hospital for. Reviving is commonly used by players who are in the hospital for long periods of time, e.g. from overdosing on certain Drugs.
You gain the ability to revive once you achieve the rank of Brain Surgeon in the Medical Job.
Reviving costs 75 Energy. This means that a Donator with a full energy bar could do two revives, while a Non-Donator could revive one player, but would have to wait for 50 more energy to perform another.
Note: You can choose if you want to receive Revives from certain people or not choose to receive revives at all.
Note: Faction bonus (Salutary) can reduce the amount reviving costs, 5 energy per upgrade -upto a maximum reduction of 25 energy. So it would cost 50 energy to revive.
