The Badlands are an extra on the game, and yet constitutes a large amount of the game, and the hardest maps of the game. Challenge players may or may not look forward to the last half of the Badlands because of the abdundance of cards, but it is the most difficult part of the game
Badlands 1-9 are for easy, simple maps, feature enemies between levels 1-5, and are intended to be done in pieces and finished before Chapter 7.
Badlands 10-19 are more legitimate maps, feature enemies between levels 6-10, and are intended to be done in pieces and finished before Chapter 12.
Badlands 20-29 are more difficult and challenging, introduce each drone holding their own deck of cards, snails and colonies, feature enemies between levels 11-15, and are intended to be done in pieces and finished before the endgame.
Badlands 30-39 are highly difficult, and Badlands 30 especially is so difficult that some players may not beat it until they have reached the end of the story chapters. Many maps have tetras. They feature enemies between level 16-20, and thus are intended to be beaten before level 20.
Badlands 40-49 are highly difficult, and have more maps which are near-impossible. They feature enemies between level 21-25, most with beam weapons and their endgame weapons, and thus are intended to be beaten before 25.
Badlands 50-60 are the hardest maps. Here, you can obtain some of the best cards like Scarab Secret (revive all fallen units found in badlands 60).
