Blizzard have announced old-gen Diablo III players wanting to upgrade to the PS4 or Xbox One version can migrate their saves onto either of the newer machines - irrespective of what format you started on.
"Played Diablo III on the PS3, but want to pick up and slay with Ultimate Evil Edition on the Xbox One?" reads the post. "No problem! Previously mowed down some demons on the Xbox 360, but are now looking to cull hordes of renegade angels on the PS4? We've got you covered."
Head on over to migrate their saves on the official site for the guide on how to do it. Diablo III: Ultimate Evil Edition releases on August 19th.
