Dead Cells contains many different routes, and if you fail, you start over at the beginning and take a whole new path. These paths are full of enemies and traps, inviting you to bring your best reflexes to survive. Dead Cells has received plenty of free DLC since it arrived on Steam in Early Access in 2017. The new DLC, The Bad Seed, gives players access to two new locations, and to access the Arboretum, you need the key to the dilapidated arboretum.
Because all levels of Dead Cells go through procedural generation, not everyone will find the Dilapidated Arboretum Key in one place. However, you can find it exceptionally early. You can find it in the prisoners' quarters where you first appear in the game.
You won't be able to encounter The Bad Seed DLC without first finding the Teleport Rune and the Vine Rune. The vine rune allows you to create a vine from the ground to access a new level. The teleport rune allows you to teleport using the sarcophagus. When you teleport to the next level in the prisoners' quarters, you should see a skeleton covered in grass, still wearing a red and blue uniform, with a pitchfork nearby. Interact with the skeleton, and you should find the key, along with the Royal Gardener outfit.
There's plenty of new content to explore in The Bad Seeds DLC for Dead Cells, with a new boss called Mama Tick.
