The latest Super Smash Bros. for Nintendo 3DS update on Miiverse confirmed Conquest mode for the localised version.
Producer Sakurai noted how the new, online multiplayer feature "Conquest" will aggregate global wins amongst specific teams within a time frame to determine a victor. "If you choose a participating fighter from the 'With Anyone' option, you'll automatically participate in Conquest."
He also noted how those who appear to be losing on purpose will be "removed from the calculations."
Conquest mode is currently running in beta.
