February Update

Hey Hackers!
We have just a couple of items to go over in this update, so it'll be short one.
First, although the manufacturer is closed until Feb. 24th for Chinese New Year, they have let us know that when they return, they will resume work on the miniatures and should have the samples for all miniatures completed around March 15th. So we should have those to share with you in our next update!
Second, we are going to be finalizing our order with the manufacturer once they return from CNY. This means we will be locking orders and charging for shipping on our next update, so please make sure your address is correct and up to date in your BackerKit survey.
If you are unsure how to access your survey, you can use the link below to find it: zerodayexe.backerkit.com
Here is how locking orders and charging for shipping will work:
1) We will lock all orders with a final notice. This will give you 72 hours to make any changes to your address and/or contact information, or purchase add-ons you may not have added during the campaign.
2) After that 72 hours, the orders will lock and we will charge the cards on file for shipping. Please make sure the cards on file are up to date and able to accept this charge. If the shipping charge cannot go through, we will not be able to ship your order.
Since we are talking about shipping, now is as good a time as any to let you know that shipping costs, as everything else, have gone up. For each region, there will be a $3-$5 increase in the shipping costs from our original estimates during the campaign. We are eating as much of the costs as we can, but we unfortunately can't take it all on.
That's all we have for this update. We hope everyone has a great and safe weekend!

January Update - Echo Artwork and Character Achievements!
9 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!
10 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!
Link's Card Art
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!
11 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.
Card Artwork for T. and Syn
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
about 1 year 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!
