Perks

Each survivor can have a number of perks (normally up to 4) which provides various bonuses, such as additional skill points or increases effectiveness with certain missions. The main leader has a special perk chosen at the start of the game which affects the entire fort. Some survivors arrive already with perks. Most perks are gained when a survivor reaches level 3, 6 or 9, after you talk to them and learn more of their backstory (Not including skill bonuses from weapons and nonweapons).
