Pretty great price for essentially 3 version of the game! And it has cross-save so you can continue playing on a different console

And all future updates are due to be free!!

We’re working on two new campaigns: Specter Knight and King Knight.
Campaigns will not be releasing at the same time. Specter Knight will be released first!
No estimated release date for any Update quite yet.
Similar to our last update, we’ll probably go overboard too. Hey! Maybe that’s why we’re called Yacht Club Games!
New campaigns will come with new Feats and Challenges for the new campaign character!
We’re also working on two new modes: Body Swap and Battle Mode!
Just like Plague of Shadows releasing with Challenge Mode, we’re planning to release one of these new modes alongside each campaign.
Battle Mode is being designed as a single screen, multiple controller, multiplayer mode and is currently not planned to arrive on handheld versions of the game. We’ll be sure to announce if there are any changes on that front.
Much like Plague of Shadows, all of the announced upcoming Shovel Knight content will be free on ALL platforms! For disc/cart and digital versions!
