Bungie's 30th anniversary celebration has brought lookalike Halo weapons to Destiny 2, and although they're technically not the real deal (Bungie doesn't have the rights to Halo since it went independent), they're still all the rage. Here's how to get the BXR-55 Battler, a thinly veiled remake of the Battle Rifle made famous in Halo 2.
How to Get the Battle Rifle in Destiny 2
The Destiny 2 30th Anniversary event is built around the 6-player Dares of Eternity game mode. By playing this game mode, players will be able to earn Treasure Keys. These can then be used to open the chests stored in the new social space called Xur's Treasure Hoard, which have a chance to drop the special weapons released as part of the anniversary event, including BXR-55 Battler.
Without a guaranteed method of unlocking specifically the BXR-55 Battler, this is the most efficient way to farm up a copy of the weapon for yourself.
Players earn one Treasure Key per full completion of a Dares of Eternity activity. They can also earn keys at random by opening Paraversal Hauls, which can be obtained by completing Starhourse Bounties. Players can pick those up behind Xur in his Treasure Hoard.
