Custom characters were added in the 1.3 update for This War of Mine. They can be selected when setting up a custom game and include the Insurance Agent, Psychologist, Photographer, Computer Specialist, Police Officer, Pharmacist, and Forester. There is also a custom character called Nurse that was introduced in 1.3 as well, however for unknown reasons at this time the occupation cannot be selected when creating or editing a custom character. When setting up a custom character, the player must choose the gender, name, in-game appearance, and character picture- either from a small library of included pictures or from a user-supplied picture placed in the Documents/This War of Mine/Portraits folder.
All custom characters have 12 inventory slots and do not have addictions.

A quick look in Cheat Engine shows the Nurse occupation being in between the Computer Specialist and Forester. Whether or not the Nurse was supposed to be implemented is only for the Developers to answer, but as of Update 3.0.3., this has not been the case, making it likely that the Nurse will not be implemented in a future update.
