The story/campaign is the underlying structure of the game. It is the "theme" of the game, and what you should expect of the whole thing. What theme does the story mode guve in Destiny 2? We can't do this alone? Friendship allows you to overcome all odds? Heck no. The story theme of Destiny is -blam!- everybody else, One guardian will take on 5 armies at once and save the entire day. Even the assault on Calus. Guess who had to do basically everything, all by themselves? Yep, the silent Guardian. How many Guardians travelled to Mercury to help Osiris? Just one. How many Guardians killed Xol on Mars? A single one. How many Guardians flew to the Tangled Shore and cause mass genocide for their ex-Vanguard in clown shoes? Only one unkillable juggernaut. ...and then, you try and tell everyone that Destiny is about teamwork and groups working together to overcome impossible odds. Yeah ok, I'll just solo another planet's worth of hive.
