Santa's Christmas Convoys
The "Santa's Christmas Convoys" campaign was a campaign that took place from 22 December 2016 to 18 January 2017. The campaign occurred simultaneously with another temporary campaign, The Hunt for Graf Spee, and required that the player owned Tier VI German cruiser Admiral Graf Spee in order to unlock the campaign and at least one ship of Tier V to progress.
The campaign was comprised of 49 different tasks spread out over 9 missions. Players progressed by earning experience (or credits) and dealing damage to enemy ships, with the final task of each mission awarding players with a Tier VI tech tree ship and a special permanent camouflage for that ship. There were achievements for both completing the campaign and completing all tasks within the campaign.
Each mission is comprised of various tasks; the campaign pins and rewards shown are granted only upon completing that particular task.
