The popular video game Mythbuster series of videos tests the myths and urban legends of popular games. The first episode that focuses on Destiny has some interesting tricks to use in the game, even if their utility is somewhat limited.
I think everyone has run over someone with their Sparrow, but did you know you can use it as a projectile as it speeds away? Time to start aiming it at mobs before you hop off. The really interesting myth is that you can avoid a Warlock's Axion Bolt simply by sitting down.
It's all interesting stuff, with more episodes on the way.
