Red War- Destiny the Game

When you want to play a video game, you log on and start doing what you wanna do. Right? Not in this case, exactly. It's a bit different when you get stuck in the game, alone- in the middle of a war, no less. There's no escape, from what you can see. Do you help fight the war or change history by acting as a spy and murdering Cayde and Ikora for the Cabal?
