What is Hollow Knight?
"An epic action adventure through a vast ruined kingdom of insects and heroes. Explore twisting caverns, battle tainted creatures and befriend bizarre bugs, all in a classic, hand-drawn 2D style." (Hollow Knight Wiki)
You are introduced to an open world full of all creatures from the Animalia kingdom, some good, and some bad. As the Knight, you defeat foes that stand in your way and discover the secrets of what used to be of Hallownest.
