Call of Duty: Black Ops 4

This achievement is quite simple, when choosing the map at the bottom right of your screen you will press and head over to the Tutorial section. When there choose Advanced Tutorial, this puts you in a match with a bot and you will be told what changes have been made to Zombies. When you complete this the achievement will pop.

EDIT: You can not get the achievement by only doing Beginner, you must either do both or just do advanced.

Thanks
