In A Plague Tale: Innocence, you will meet many characters who will accompany you during your adventure. Although you have to be careful not to get killed, and Amicia's brother - Hugo - in addition, slows you down, he also can help you get into inaccessible places. Therefore, issuing commands is an important aspect of the gameplay. Below, you will learn how friends can help you.
Most often, you will use the help of Amicia's brother. Hugo will be able to make his way through little holes. Thanks to this, he will be able to open doors for you or get you the items necessary to proceed. If you are stuck in some place, look around for small holes or windows. You can order him to go through these.
On your way, you will also meet Melie. She's a burglar and will appear at the end of Chapter V. She has the ability to pick locks. During the stages in which she appears, you will find many closed doors and chests. If you want to open them, you have to give her the appropriate command.
The third friend with unique abilities is Rodric. You will meet that guy during a visit to the University. He is characterized by high strength. He can pry open doors, but his most important skill is silent elimination of opponents. You can use him for more organized actions, and elimination of enemies in more highly protected places. He will not attract so much attention as your slingshot.
In addition, all the comrades can help to solve the environmental puzzles that you encounter. At some stages, you will need actions such as pulling a certain lever.
