I finished both campaigns today, resistance and security. I unlocked the achievements: You've escaped the ark, You saved the Ark, and Tough as Nail (completed it on Hard - Solo). Noticed after they unlocked the achievement: The story has just begun achievement did not unlock. That achievement says win both story campaigns not including what-ifs which I did. Anyone else have this achievement not unlock?

Not certain but on the final mission for each faction did you choose the "Win and End Campign" Option? this through me at first too and I had to re-beat each final mission. That may be your trouble *Shrugges*

Yeah, I did chose the "Win and End Campaign" on both. And it went one to show the ending scenes. Weird since the other achievements came up after I finished the campaigns.

Yeah bro, don't know then. I got mine after I saw the resistance finale trailer. Maybe spend a few hours in Campgin and beat it again. Granted, its a pain but its not like its a long game :/...thats all i got man...sorry.

Not sure do the What-if missions and see what happens

Yeah, going to do the what-if missions and see if maybe that springs it. If not oh well I have had others that did not unlock.

Not sure. I got the achievement no problem. Did you complete the what-if missions? For both sides?

did you do this on the same character if not you dont get

and it sasy exclud what ifs
