This Mission is located in the same place as Mission 12. The goal of this Mission is to retrieve the catapult. So if you destroy it when it's under Karmen control, you'll fail the mission. The catapult is so weak that you can't play this mission in stormy weather, because the thunder will easily destroy the catapult. Do not bring any piercing ranged weapons, flame weapons, stew that gives you ignite chance, or Rarepons that has any ignite chance, like Gyaba.
