If there's a single word to describe Destiny 2, it's disruption. In the sequel to Bungie's popular shared-world shooter, the Guardians of Earth have finally met their match with a new villain who's got his eyes on The Traveler. Our heroes, with their powers stripped away and all their gear destroyed, are pushed back to square one and have to relearn what it means to be a true Guardian of the Light. Though it's sad to see our valuable Exotics fade into the ether, this turns out to be a blessing, as the next adventure for our characters will bring new challenges, new rewards, and an even greater feeling of satisfaction when succeeding in the next big battle.

Let's take a look at five of the biggest changes in Destiny 2.
