Hollow Knight screenshot from the The Grimm Troupe trailer

If you've already completed everything Hollow Knight has to offer, you're in luck as the developers have just unleashed the second major free update. The Grimm Troupe brings with it a new lengthy quest and accompanying boss fights, 4 new charms that each come with unique abilities and skills, a bunch of new enemies to fight and strange creatures to befriend, and perhaps most importantly for long-term players, some much-needed quality-of-life changes.

The most recent trailer won't exactly give you a good look at the gameplay side of things, but it should help you get into the right mood. You'll find it right below, along with a brief list of features and changes. Have a look:

• New Major Quest – Light the Nightmare Lantern and summon the Grimm Troupe to Hallownest, if you dare! Take part in a twisted ritual that stretches the breadth of the kingdom and bestows the player with a powerful new ally.

• New Boss Fights – What epic quest is complete without epic show-downs? Get ready to face off against a dark new foe and a twisted scarlet spectre. Who are they? What brings them to Hallownest? We won’t spoil the surprise!

• 4 New Charms – We’re going all out with the quest, but that’s not enough! Your charm range is also expanding, granting unique new aids and abilities. You’ll have to discover their powers for yourself, but their appearance may give a few hints.

• New Enemies – The arrival of the Troupe doesn’t just mean enormous boss encounters, it also brings new smaller (but challenging!) foes to test your nail and spells against. Your Hunter’s Journal is going to be overflowing by the time your done!

• New Friends – Grimm’s clan may appear scary but they aren’t all bad. Get ready to befriend a new bunch of weirdos, including one who offers a very special service for players flush with Geo!

• New Music – Tying this whole cavalcade together are all new spooky and spine tingling tracks by Christopher Larkin. Get ready to feel the fear!

• Map Markers – In a world as big as Hallownest finding your way is the greatest challenge of all, and you’ll now have an extra tool in your cartographic journeys with custom Map Markers! Place them anywhere on your maps to remember a point of interest, a difficult foe or an item just out of reach.

If you've somehow reached the end of this article without ever actually trying Hollow Knight, you might want to head on over to Steam and GOG as its currently on sale. Its one of the best Metroidvania games I've played in recent years, so I would definitely recommend you give it a look. Have fun!
