Destiny 2 lets players engage with the story and gameplay as they please, running old or new campaigns in any order they might prefer, learning all the mechanics by trial and error, or checking them out online. Players being at liberty to do what they want is core for Bungie, and it shows in Destiny 2's many customization options for cosmetic choices and actual player builds. Among these options, Destiny 2 players can use mods to change the way their builds work, have a plethora of different weapons and armors to pick from, and are able to unlock many Exotics.
