Similar to Campaign Heroes, FIFA World Cup ICONs will replace their Base & Mid version while available in packs. Some FIFA World Cup ICONs may only be available as Player SBC or Objectives rewards.
Campaign ICONs that are available in Packs may have that version released in Squad Building Challenges as an ICON SBC at least 2 months after they are first made available. For example, FIFA World Cup ICON Bobby Moore may receive an SBC starting January 25th.
Similar to Campaign Heroes, Campaign ICONs will appear in Rare Gold Packs such as those found in Upgrade SBCs or FIFA World Cup Swaps Rewards.
