The last generation of consoles was known for introducing smaller, downloadable games to console players, and one of the most successful Xbox Live Arcade releases on Xbox 360 is getting an upgrade to the newer Microsoft machine.

Castle Crashers Remastered is coming to Xbox One on September 9 for $15, according to developer The Behemoth. The studio sold millions of copies of Castle Crashers, which is a four-player action-adventure beat-’em-up, on the Xbox 360 and eventually PC as well. So it makes sense that the company would want to rerelease its most popular game so far — especially considering the original came out seven years ago.

Of course, the success of Castle Crashers means that you likely already own the game for Xbox 360 — well, if that’s the case, then you’ll actually get the Remastered version on Xbox One for free. The only requirements are that you need to have an active Xbox Live Gold account and you need to download the game before September 20.

If you own the original for Xbox 360, have Xbox Live Gold, but wait until September 21? At that point, you’ll have to pay human dollars to get the Remastered game on Xbox One. But it will only cost you $5 instead of $15 or you could play the original, non-remastered version on your Xbox One since The Behemoth has promised backward compatibility.

Developer The Behemoth revealed Castle Crashers Remastered earlier this year, but today’s announcement included some new details about what exactly about the game is “remastered.”

Here are some of the most notably improvements:

  • Improved frame rate to 60 FPS instead of 30 FPS.
  • New multiplayer mode.
  • Higher-resolution textures.
  • Better performance in the main game and online.
  • Better matchmaking.

I love me some Castle Crashers, so I’ll have my Xbox One booted up on September 9 to get in on this action. Here’s to rocket-poop-propelled deer!
