You will earn (well, at least should be earning) these decorations in-order as follows ('1.' being the first decoration, and '12.' being the last): Annoyingly, this achievement can be glitchy. I've kept it spoiler free, but you'll understand it better after the game is over.Ħ. Go and finish at least one run of the campaign before reading this page. This achievement will probably take you (depending on skill and luck) somewhere between 40-80 hours to complete.ĥ. Be prepared to join some gaming sessions - if you don't like playing with other people this achievement probably isn't for you.Ĥ. The list is in order of appearance, not in-order of how you're going to get the decorations, however, I will give an idea of how you'll unlock them as you progress.ģ. If you cannot finish the training simulator on Realistic first, then don't even bother going for this achievement.Ģ.
