Ok so this campaign was one of the worst I've played I feel like bungie gave us a huge middle figure when it came to the campaign. My 4 year old niece could come up with a better story then this. It was so vague literally. Give you opinion. Edit** They could have save other planets for later games like Mercury, Saturn, Jupiter, Pluto but they could have had more places available to play on Earth, moon, Venus, and Mars. Especially Earth I feel like they should have done more on earth make it seem like you took back some of earth then for Venus and Mars and the moon it'd be like these are other threats and and the battle have only just begun. That's just a idea and my opinion though.
