Sledgehammer Games has confirmed that the new Royalty Elite Variants and the SAC3 non-akimbo variants are set to be available only on Xbox One, PS4, and PC. They have no plans to bring these weapons to the Xbox 360 and PlayStation 3 due to hardware limitations and restrictions.
PLEASE NOTE: These Elite weapons are only available on the current generation of consoles (Xbox One and PlayStation 4) and PC. We are dedicated to providing a wide variety of content to all AW players wherever possible, but in some cases are unable to include additional content on the previous gen consoles due to hardware limitations.
The new weapon variants are available starting today on Xbox One via Advanced and Regular Supply Drops. The new variants are coming soon to PS4 and PC. Learn more here.
