How to unlock the Hello darkness... achievement in Odium to the Core - Definitive Guide
Nightmare Levels are a harder variant of the level. But this isn't about completing them, it's just about unlocking one. What do you have to do? Complete all 3 gears for a level.
While some of you may think you did this, it doesn't count for the Level 1 tutorial. You need to do in a non-tutorial level. So I'd recommend doing it for the second level since it's the next easiest.
The secrets and score gears shouldn't be too bad. The orbs one will be the big challenge. You'll need to get all of them. Just make sure if you miss one to take a death and go back to the checkpoint. You can die as many times as you need to get all of them.
Keep in mind that taking the secret paths will have the same number of orbs as the main path so either route is acceptable. You won't miss orbs by taking one path or the other for secrets.
