January Update - Echo Artwork and Character Achievements!
7 months ago – Tue, Jan 20, 2026 at 10:32:20 AM

Hey Hackers! 

We hope you all had a good holiday and a safe time jumping into the future that is 2026! We've just got a couple of quick topics, one if which is of course...more artwork!

CHARACTER ACHIEVEMENTS

Before artwork though, we wanted to talk about Character Achievements and get some feedback (as well as ideas) from you!

Below is the current list of achievements for the 6 characters in the base game: 

The list is still being tested and tweaked when necessary. Our current thoughts on these achievements are that they are just for your own personal satisfaction - something for you to try to achieve while playing the game. 

We have played around with the idea of "unlocks" for these achievements, but to keep manufacturing costs down, the content that would be locked behind these would have to be current content that is already in the game. So our question to you is - Would you prefer we "lock" content behind these achievements, or keep them as personal achievements?

We are also discussing these achievements in our Discord and we are looking to add 1 or 2 more per character, using ideas from you! So if you are interested in giving your ideas for achievements, we'd love for you tojoin our Discord and share with us! You can also let us know in the comments here.

ECHO ARTWORK

We'll end this update with some awesome new artwork by Daniele Nicotra for Echo's starting Hacks. Let us know what you think!

December Update - More artwork complete + first miniature sample - We want your input!
8 months ago – Thu, Dec 11, 2025 at 06:17:42 AM

Hey Hackers! 

We hope everyone has been doing well! We are pushing along through the artwork and miniature sampling process with the manufacturer and have some great updates to share with you all, so let's load right in!

NEW ARTWORK

We'll start with our normal dose of new artwork - we've got Link's player cards, along with another set of Mods, this time from the corpos at Hanzo Cybernetics!

Hanzo Cybernetic Mods

With their sleek, almost alien-like design, they are a favorite for high-end clientele. These mods have powerful abilities, such as scanning enemies to calculate their next moves and even keeping enemies from moving away from you. Below are a couple examples of the mod cards, along with the illustrations for each Hanzo Cybernetics Mod!

SHADE MINIATURE SAMPLE

Below are some images of the first miniature sample we've received from the manufacturer. We are very happy with the quality of the miniature, but we want your feedback on one aspect for Shade's miniature - the color!

Originally, the idea was to create the miniatures with acrylic accents that matched the colors the characters use on their player boards and cards. In the images below, Shade's miniature has blue as the color (which is how we have shown it on the campaign page), but his player color is actually grey. So here's our question to you:

Would you rather us keep with the player colors for Shade and have it be grey (in reality, we'll probably choose white or dark grey to make it pop a bit more), or should it match the artwork of shade, with his mask and camo suite having blue accents? Let us know in the comments!

That's all we have for now. We are sending over every other miniature to the manufacturer within the next week or so and hope to get some sample images of each one soon!

We hope you all have a safe and happy holiday and we'll see you in the new year!

October(ish) Update - T. and Syn card art, more minis, and starting the moulding process!
10 months ago – Tue, Nov 04, 2025 at 07:02:28 AM

Hey Hackers!

Apologies for the late update this time around - October is a busy month for us and we love Halloween so we kinda lost track of time watching scary movies, eating candy and enjoying the festivities! This update will be a quick one, but we have some new art as always, plus a new miniature model for you to check out!

First though, we wanted to let you know that we have began the process of creating the miniature molds with the manufacturer. We are starting out with 1 model to work through the kinks and make sure the process runs smoothly for every other model. This is the longest process of manufacturing so we are expecting it to take a good amount of time, but Black Magic is a pro at creating miniature models and their knowledge will make the process go a lot smoother!

Below, you can check out some new artwork we've received, along with the model for Syn's miniatures.

Syn Miniatures Model

We'll be back at the end of this month with some new artwork (including the final set of mods!) and hopefully an update on the miniature modeling process!

As always, if you want to help play test the game, please join our discord and ping me so we can set up a session for you to try it out!
 

Until next time,
-Hacker Kat & Zach

 

September Update - Miniatures + Solo Mode
11 months ago – Tue, Sep 23, 2025 at 06:58:25 AM

Hey Hackers! 

In this update, we've got some awesome new miniature renders from Black Magic that we're excited to show you! A few people here and on discord have also requested some more information on solo mode, so we'll jump right into that first! 

Solo Mode

In Solo mode, you choose your character as well as a second character to be your AI companion. This character won't use Hacks, but will still be able to upgrade their stats, equip mods, and use items throughout the game. Instead of Hack cards, each character has their own set of 6 AI cards. During the initiative phase, you will flip one of these cards over, revealing their initiative, movement, range, and attack for the round, as well as any special abilities they may have. 

Example of a T. AI card (left) and a Kit-E AI card (right)

We really don't want solo players to miss out on any aspect of the game, especially the cooperation. This system allows you to have complete control over your companion, without having to manage/build a second deck, worry about playing hacks/matching programs, or worrying about what initiative to play. It also still allows you to use the Flux ability of your character's Hacks to assist your companion.

To make up for the lack of hacks your AI companion has, we've made them a bit stronger as well and gave them the ability to heal instead of move on their turn. This helps them feel less vulnerable while still also allowing them to do some serious damage! 

We are still working on solo mode to make sure we strike that balance of keeping most mechanics in the game while also not overloading the player with too much upkeep/info.

For those who will play solo, here's a question you can help us with!

Do you feel the AI cards should tell the players if/when the companion activates the skills on their player board, or should players be able to use the companions skills at their discretion?

Let us know what you think in the comments!

Miniature Models

Below you can check out some W.I.P miniature models for Link, Echo, and T.:

While we work on the others, we'll try to share some renders with the effects that will be acrylic so you can see the pops of color that they'll have as well!

If there is any part of the game you'd like more information on, please let us know in the comments and we can try to get it into one of our future updates!

August Update - New Artwork (More Mods!) + Gen Con recap
about 1 year ago – Mon, Aug 18, 2025 at 11:42:16 AM

Hey Hackers!

After getting a bit of con-crud from Gen Con, we are finally on the mends and getting back to normal. Besides that, Gen Con was fantastic as always! We were running constant demos of ZeroDay with almost no breaks in between for most of the con. I genuinely don't think a single person walked away not having enjoyed the game! We were also excited to meet those of you who backed the game and stopped by the booth to say hello. It was truly a great time and made us even more excited for ZeroDay!

We've jumped right back into play testing and getting new artwork. We also picked up a few new members in the Discord who have been play testing the game and giving a ton of feedback. Playtesting and feedback is invaluable in making the game the best it can be, so we wanted to thank those of you who have been helping with that!

Kyushi Enterprises - Military Mods

This corp creates military-grade cybernetics, usually only available for gov. contracts (but we know a guy). These sleek mods can do everything - manipulate your shift tiles, use your life to draw extra cards, or even deal damage back to enemies when they cause you to lose life! Check out a couple of our favorites below, along with the illustrations for each Kyushi Mod!

New Enemy Standees

We also recently updated our enemy standees to make them look cleaner and more polished from our prototypes. We think these new standees give the enemies more personality and make them come alive on the board!

Next update we are hoping to have a couple more miniatures to show you, along with more artwork with the "Hanzo Corporation" mods being completed!

Is there something you want to get some info on in the next updates? Let us know in the comments!
