Game update

CrossCode x Quantum Protocol Collab

Hello everyball!

Starting today, you will find the cast of CrossCode in (yet) another indie game: the deckbuilding card game Quantum Protocol! For the occasion, we also release another hotfix for CrossCode, adding bunch of fixes, a tiny bit of content, as well as a small group of guest characters!

CrossCode x Quantum Protocol

With today's update, Quantum Protocol will include a whole set of new cards featuring several CrossCode characters as well as the four elements for you to use!

Here is an overview of all newly added cards:

Those cards work in a unique way reflecting the mechanics of CrossCode. You can read more about it in this blog post

You can get Quantum Protocol on Steam here:

Hotfix version 1.4.1-3

We released another hotfix, mostly fixing bugs and spelling issues. There's also a few small content additions, including:


A new Supporters' Cup to be found among the custom cups, adding a few more quest related boss battles to the arena.


A new room above the Rhombus Square Item Shop assembling a whole bunch of traders for all kind of items.


A couple of guest characters from Quantum Protocol just vibing in a certain inn. Have fun finding them! Unfortunately, with no new dialogs this time.

And that's it!

Meanwhile, the CrossCode New Home DLC is currently being ported to consoles and we'll let you know once a release date is certain.

And otherwise, we're all hard at work on Project Terra, currently working on a lot of things, including a new animations system:

We'll likely create another post about Project Terra in the future, showing things a bit more in detail.

And that's all for today! Until next time!
