Please how do you revive someone. How's it done 

You'll need to complete the following Medical Degree courses in the University:

MED1000 - Biology: Life, the Universe, and Everything (7 days)

MED1020 - Dissecting the Mysteries of the Human Body (14 days)

MED1210 - Cut and Stitch: A Whirlwind Tour of the World of Surgery (28 days)

After that, you're good to go; you'll see a heart icon on player Profiles and on the Hospital page, and a 'Revive' button next to your own Cartel members' names on the Cartel page. You'll also start seeing your Revive Skill on the 'Home' tab 😊 

Cool

This is real useful to be honest
