Campaign on legendary and Spartan ops.

So for some odd reason I went to select the campaign mode and all my levels dissapeared and for some reason thebvid docs are gone too so I want to refined them and finish the campaign on legendary again. Not sure how this happened but I would like to have a 4 man team to do it since it goes faster and I have time to kill Gamertag is EAPADAS03.

Also looking for a spartan ops team I mean we can wear same color armor or not but when I play I aim to not die at all or die very minimal I’m down to play on easy when playing normal mode and obviously it will be on heroic or legendary when a four man team but want players who can be strategic rather then rush in and get killed 40 times in one match of spartan ops.
