Decided to unlock legendary armour and 117 tag just completed campaign on legendary got 3 achievements but no armour later checked online only to find out needed to be connected to xbox live only played three levels while connected just seems stupid to have to play through single player story online to get unlocks why cant waypoint recognise game completed on legendary and unlock bonuses
Yeah happened to me and my bro. Luckily it was only the last mission. Just replay them and check connection.
It’s connected to the Commendations, and you can’t complete the Commendations offline. It’s kinda stupid, but that’s the way they did it, so you just have to deal with it for now.
