Maybe I missed it, but I can't seem to find an answer anywhere about this. My bro and I were just starting this game it had some message about a Guest not being able to get achievements. He's got his own account and is signed in, but we quickly have found that he's not getting any achievements. Is there no way for him to get them in co-op without being the host/1st player?
Not sure that I've seen a co-op game where a partner couldn't get any achievements, which seems odd if you're trying to encourage cooperative play.:/
Any help would be appreciated.
