A new kind of limited-time event is coming to Destiny 2 next week, and it’s all about inspiring Guardians to use the most classic of melee weapons: It’s time to bust out your best heavy swords.

Starting at Destiny 2’s weekly reset on Sept. 3 and lasting for one full week, swords in the Heavy slot will generate ammo. That’s right, infinite ammo for swords for one whole week. Get ready to slash up a storm with some of the game’s most fun weapons.
