Apparently theres a new exotic mission but i dont see it anywhere and im pretty sad. Finished the campaign and every other lightfall quests so theres no reason for it to not be available.
If you heard of it, where ? They did not mention how to get it ? Basicly, shoot 6 flying cube in the gulch (edz) and find that big flying portal in the air, look under it for a cave. Secret mission is not meant to be visible, otherwise that would not be a secret mission
