Can someone tell how in the hell can I check which mission on the campaign I have completed on Hardcore or any other difficulty. I have check everywhere I can think of but I haven't found nothing yet and I seriously don't want to do a whole campaign just to check which mission I didn't do so I can complete a challenge.
Go to Challenges > Campaign Assignments > Mission Complete > then: "Finish all Missions on the hardest difficulty" ... and click "TRACK" (bottom right).
You might also want to track "Challenge Expert" and "Mission Ready" (dogtag collection, use YouTube video to find them all).
I did track the challenge for the Hardest Difficulty and I already found every single collectible. But for some weird reason even me completing every mission of the campaign twice on Hard Core the challenge does complete itself. I think my challenge is bug or something because I even did all the achievements of the campaign and still that challenge of "Finish all Missions on the hardest difficulty" stil saids 8 of 9 mission even me doind them twice on Hard Core.
For those having the same issue as me, Don't worry I found how to fixed. Basically if you restart a mission again will you are doing the campaign because you forgot a collectible, Don't do it. Leave the collectible for now and just end the campaign so you can get the challenge of 9 of 9 Hardcore Mission Completion. When you get that challenge them you can go back into the mission that you left the collectible.
