This achievement is for going through all of the tutorial entries located under "Single Player" > "Tutorial", and can be unlocked at the very beginning of the game. There are ten entries in all, and each will get a green X mark in the box next to the entry once completed. Most simply require you to attempt the moves related to that entry, but others are simply an infodump. If it says to press
to End Tutorial, simply press it to finish your current entry.
