This is my last campaign achievement and I'm hoping to find partners to do a run through on Mission 4 to get it.
I'd also willing participate in helping others complete their Heroic or Legendary co-op campaign attempts.
I just completed solo Legendary so I think I would be somewhat useful in that regard.
Am I the only one that thinks that the lack of the an automated campaign co-op search function in Halo 4 is big 'fail' on the part of 343 Industries?
I see references that this was a post-launch addition to Halo Reach but that is not what I remember.
Either way it just makes me want to play Halo 4 that much less now that I'm done with my own Legendary campaign run.
