It turns out Mass Effect: Andromeda was supposed to introduce at least ten new types of aliens. The developers of the game told about this in an interview with reporters.
According to Bioware writer Niel Pollner, new content was not added to the game due to budget constraints, formatting limits.
Dorian Kieken – the design director of the Mass Effect franchise at the beginning of Andromeda’s development – explained that some of the aliens the team came up with for Andromeda had rather unusual looks. However, they decided not to use these developments – most likely, in order to make it easier for cosplayers to transform into new characters.
Recall that Mass Effect: Andromeda was released on PlayStation 4, Xbox One, and PC in the fall of 2017. The game was extremely coolly received by the specialized press and was smashed by gamers.
