Up to today many though that Australian=based studio Team Cherry, and the talented team behind Hollow Knight, were simply working on DLC or add-on content. Well, turns out that they've been hard at work on a brand-new game. A sequel called Hollow Knight: Silksong that features a brand-new kingdom, enemies, quests, and more.

Here's the surprise reveal trailer that dropped alongside the announcement.

• Discover a whole new kingdom! Explore coral forests, mossy grottos, gilded cities and misted moors as you ascend to the shining citadel at the top of the world.
  
• Engage in lethal acrobatic action! Wield a whole new suite of nimble moves as you dance between foes in deadly, beautiful combat.
  
• Craft powerful tools! Master an ever-expanding arsenal of weapons, traps and mechanisms to confound your enemies and explore new heights.
  
• Solve shocking quests! Hunt down rare beasts, unearth ancient mysteries and search for lost treasures to fulfil the wishes of the downtrodden and restore the kingdom’s hope. Prepare for the unexpected!
  
• Face over 150 all-new foes! Beasts and hunters, assassins and kings, monsters and knights – defeat them all with bravery and skill!
  
• Experience a stunning orchestral score! Hollow Knight’s award-winning
• composer, Christopher Larkin, returns to bring melancholy melodies, symphonic strings and heart-thumping, soul strumming boss themes to the adventure.
  
• Challenge Silk Soul mode! Once you conquer the game, test your skills in an all-new mode that spins the game into a unique, challenging experience.

And in a great move Team Cherry notes that the Kickstarter backers that made Hollow Knight a reality will be entitled to the sequel at no additional cost. Very cool.
