The creation of the protagonist characters in Mass Effect Andromeda is very different from what we knew from the previous parts of the series. There is an option to customize the appearance (or stick to the characters prepared by the developers) or gender, but there is one major difference – there is no class system in Andromeda. You won’t be able to choose from classes like Adept or Infiltrator. Instead, you will have almost complete freedom to choose the abilities for your character.
In this and subsequent chapters, you will learn all about the character creation process – how the appearance of your character, as well as his/her twin, will affect the appearance of Alec Ryder (the father of the Ryder twins). In addition, you will find information about all 6 trainings (class system in Andromeda) and the consequences of choosing each of them.
Note – Please remember that the information provided in the following chapters is only a general guideline. For example, there is nothing stopping you from turning a character with security training into a pure biotic.
