Following yesterday's weekly reset, we now have Armsday in Destiny. For those unfamiliar, every Wednesday, Banshee-44 (the Gunsmith) will offer Guardians a fresh batch of weapons to test without having to purchase them. Each weapon also comes with a bounty (field test) that will earn you reputation with Banshee-44 if you complete it.
Hakke Test-A (Auto Rifle: When zoomed, this weapon fires slower, but causes additional damage) – Use against Cabal to gather data for Hakke's armament scientists.
Suros TSA-10 (Auto Rifle) – Make precision kills to gather data for the Suros research department.
Hakke Test-A (Pulse Rifle) – Make precision shots with this weapon to gather data for Hakke's armament scientists.
Suros TSP-10 (Pulse Rifle) – Use against Hive targets to gather field data for the SUros research department.
Hakke Test-A (Sniper Rifle: Kills with this weapon increase reload speed for a short time) – Use against Cabal Centurions to gather data for Hakke's armament scientsts.
As a reminder, you don't need to complete the bounties, but doing so will earn you reputation with Banshee-44 which, as you increase in rank, will allow you to place orders for powerful weapons.
