There are three complete courses which each comprise five expeditions. One additional expedition is unlocked after obtaining key items associated with clearing the previous three courses for a total of 16 expeditions.
The Meeble Burrows guide maps below are intended to complement the information on the individual expedition pages and may not contain all information necessary to fully understand a particular expedition.
The following table shows the equipment rewards unique to Meeble Burrows in Batallia Downs. Approximately half of the available equipment drops from bosses in level 5 expeditions, and the remainder is purchasable with Research Marks from the Burrow Researcher or Burrow Investigator after completing the associated course of Batallia Downs Meeble Burrows expeditions. An additional category, Total Completion Rewards, is unlocked once all 12 of the #1 through #4 expeditions have been completed to goal 3 (boss expeditions are not necessary for this category of rewards). Whenever new items are unlocked for purchase with research marks, a message stating that "new items are available for purchase..." will be displayed at the end of the expedition, after using a whistle to exit.
