Dust An Elysian Tail

To perform a 200 hit combo, you will need to earn your Dust Wind ability and learn how to use Fidgets projectiles. You can earn this smaller 200 hit combo early in the prologue before chapter 1. Just progress through the chapter to the area in the video, then let loose with the combination of projective and wind attack.

Don't worry too much about not earning this achievement. You'll do many 200 hit combos throughout the game without even trying. You can also earn it alongside the 1000 hit combo achievement.

Using only melee combos won't earn you many hits. Use Fidget's projectiles in combination with Dust's dust storm ability to score lots of hits quickly. Keep in mind that getting hit and having your chain broken, even after surpassing 200 hits, will NOT earn you the achievement.
