Hello

I am trying to get all the mission achievements for Fallout 4, I am playing on Xbox one... I am trying to follow this guide:

(it wont let me post the image, sorry)


I have just started Liberty reprimed, The next mission is Blind betrayal, where it says "(DO NOT COMPLETE BLIND BETRYAL YET!!!!) - And you complete it later on... Would it be best NOT to even start that mission? (even though ive been given it) or do I have to do part of it up to a certain point?


I would prefer to of been given the mission, but not even start it.... unless 100% I have to start it and get upto a certain point, and not complete it and then go ahead and start Synth retention


I hope somebody can shed some light on this

Thank you for your time
