Movement in Beyond is done with the left analog stick. Whenever white dots appear onscreen, move the right analog stick in their direction to interact with the environment.
Jodie can switch to her entity Aiden almost at any time if you press triangle. As Aiden you can move around freely and do, well, nothing most of the time. You can sometimes interact with objects by holding L1 plus the analog sticks down. At other times you can take down enemies or control them by respectively pulling the analog sticks towards the middle, or pulling them away from each other.
In interactive cutscenes, such as physical combat, you will usually have to use the right analog stick whenever the game slows down. It is important to always watch how JODIE is moving, and in which direction she is moving in. The controls you execute enforce her movement, in other words, if she is moving left, you will have to push the right analog stick to the left, and so on.
