Jesse Faden is a very strong hero. Over time, you will be able to improve her skills. The problem is that skill points aren't as common as they might seem. This chapter of the Control guide will tell you how to get more skill points and max out the character.
There are several ways to get skill points in the game. First, the main missions give a lot of points by completing subsequent objectives. Thus, your character will be regularly strengthened by making progress in the main campaign.
Another way to get skill points is to get them by completing side missions. This way you will get quite a lot of points - especially when doing quick tasks like What a mess! All side missions can be found in separate chapters of the guide.
However, you will soon find out that even after completing the game and all the side missions... you won't have enough points to max out the character. To do this, you have to hunt for hidden rooms - reaching to a hidden room will give you 1 skill point. Control has many secrets, however, we have prepared a section that contains a list of hidden rooms. This way you will be able to max out Jesse's skills and try to get the platinum trophy/to achieve 100% completion of the game.
