Hollow Knight is a 2D adventure game for PC, Mac and Linux, currently in development by Team Cherry http://teamcherry.com.au/hollowknight/
Beneath the fading town of Dirtmouth sleeps an ancient, forgotten kingdom. Many are drawn beneath the surface, searching for riches, or glory, or answers to old secrets.
As the enigmatic Hollow Knight, you’ll traverse the depths, unravel its mysteries and conquer its evils.
