Release it in the Summer of 2013 as a full Campaign DLC. No episodic content. Full 5-7 hour campaign.
This would give them more time on mission and level development along with making the playable missions more relevant to the CGI cutscenes. However, it seems in episodes 6-10 they are more relevant compared to the first half.
This would have also given them the opportunity to incorporate Firefight 3.0
Just look at the suggestions made by the community that they could have used.
Don’t get me wrong, I like Spartan Ops. The story is great and can’t wait to see the finale next week but it could have done so differently while adding in more content to the game.
