Can i Complete Mythic Difficulty in Co-op

Im trying to get the LASO awards but im tired of starting over on the first mission, can i get them while doing co-op or does it have to be in single player?

Straight from the mythic forum post:
“More specifically, Mythic Difficulty refers to playing the game on Legendary with all skulls activated. We like to refer to this as SSLASO to incorporate both single player and co-op modes. No, that extra “S” wasn’t a typo. Unlike simple SLASO (Solo Legendary All Skulls On), SSLASO stands for “Single-Segment Legendary All Skulls On”, meaning the player must make it through each mission individually on Legendary with all skulls on, from start to finish, in one go. No deaths. No saves. No reverting to the previous checkpoint in co-op mode. This is a challenge to be feared.”

On that note have you completed the campaign on legendary with any skulls on throughout the process.

You can do it co-op and still unlock the emblem and XP.

However, you’ll need to do all of them in co-op for it to count, (you can’t do some co-op, some solo as it won’t unlock for some reason).
