The Bonus Mission Pack is a mini-add-on where the player can witness certain events in the history of the current Guild Wars universe. It contains four unique missions, all single-player, all across the three continents (campaigns), where the player assumes the role of the story's hero.

Those are:

- Saul D'Alessio and the rise of the White Mantle in Kryta.
- The story of Gwen after the Charr invasion in Ascalon.
- Master Togo's history in the Canthan Tengu Wars.
- The Battle of Jahai, where the Elonian hero Turai Ossa defeats the undead king Palawa Joko.
