Sometimes a treatment fails or you won’t cure a patient in time, the patient dies.
When a patient dies there is a chance the patient will remain at the hospital as a ghost.
The ghost can only be captured by a janitor with a ghost capture skill. It looks like a sad ghost.
Do this 100 times and the achievement will unlock.
NOTE: The achivement tracker on the xbox might not track your progress properly, but the ingame Career menu will track correctly.
Please leave a comment if the guide is wrong in any way :)
