20% Discount, Tutorials and Infection Improvements

2 Jun

Hello, Scientists,

To celebrate our new 20% discount, which will run until June 15, we are releasing a new update focused on infection balance, clearer experiment feedback, and new tutorial support for Assistant and Experiment Logs systems.

Improvements

Slower Infection Growth

Player infection now increases more slowly.

The infection growth rate has been reduced by 20%, giving players more time to react, craft vaccines, and manage infection pressure during a run.

This should make infection progression feel less punishing, especially during the early and mid-game.

Improved Experiment Logs Feedback

Experiment Logs feedback has been rewritten to be clearer and more natural.

Failed experiment feedback should now give more readable guidance without directly revealing the correct classification or exact solution.

The goal is to keep the puzzle feeling intact while making it easier to understand what direction your next attempt should take.

Better Comparison Between Attempts

Experiment Logs can now give better feedback based on your previous attempt.

This should help players understand whether a new blueprint attempt is getting closer to a useful result, becoming more stable, or moving in the wrong direction.

This change should make repeated testing feel more meaningful and less random.

New Assistant Tutorial

A new Assistant tutorial flow has been added.

This tutorial helps explain how assistant-related systems work and can be reopened with F1 from the related screen.

New Experiment Logs Tutorial

A new Experiment Logs tutorial flow has been added.

This explains how to read experiment feedback and use the logs to improve future blueprint attempts. It can also be reopened with F1 from the related screen.

Fixes

Assistant Zombie Fight Fixes

Fixed several issues related to assistant behavior during zombie fight sequences.

Assistants should now handle fight cleanup and pathfinding more reliably after combat-related actions.

Assistant Pathfinding Stability

Improved assistant pathfinding recovery in cases where an assistant could get into an invalid movement state.

This should reduce cases where assistants fail to continue their task correctly after movement interruptions or combat-related behavior.

Closing

This update is mainly focused on making infection pressure more manageable, improving experiment feedback, and helping players better understand Assistant and Experiment Logs systems.

More tutorial improvements, laboratory automation updates, visual polish, and gameplay clarity refinements are still in progress.

DNA sequencing

Why does the game explain the DNA sequencing part so poorly? I have absolutely no idea what the rules are; any custom virus is not viable. Please help me figure out how to create the sequences correctly?

Suggestions and Bugs

- When picking location map doesn't let u move around thru it. - PLEASE change it so while on the pc we can change the tabs, not with mouse wheel up/down before sitting down. - Make it constantly show the tutorial. - Add running. I got boored half way tbh. This really needs more work....

一些个人看法和建议

First,your sincere attitude gives me hope for this game. But I sincerely hope for you,the developer,to accelerate the development progress of the game,for example,by developing more new gameplay and monster types. Or,with greater immediacy,behold the monsters of your own creation as they lay waste to the world! I eagerly await it!...

Tutorial does not wor

I wanted to try out your demo, so I went to the arrow on the PC and clicked through everything as described in the tutorial, but it didn't work! In other words, all you can see is the lab that you see in the trailer... Or am I doing something wrong?...

New Infection Tutorial and Market Balance Changes

8 May

Hello, Scientists,

This update focuses on making the infection and vaccine flow easier to understand while softening the Supply Market economy balance.

New Features

New Infection Tutorial

A new infection tutorial has been added.

The tutorial appears when the player reaches 50% total infection for the first time. It explains the infection indicator, the choice between crafting viruses and vaccines, and how to use vaccines during gameplay.

This tutorial is especially important for the early game, since your character starts infected with TcA, and your first major goal is to produce a TcA vaccine.

The tutorial will only appear once per save/session, but it can appear again when starting a new game or after clearing save data.

Improvements

Clearer Vaccine Guidance

The infection tutorial now gives players clearer guidance on the vaccine flow.

It explains that vaccines can be crafted as part of the same biological development loop, and that they can be used with V when needed.

This should make the early infection management loop easier to understand, especially for new players.

Supply Market Balance Adjustments

The Supply Market economy has been adjusted to feel less aggressive as the game progresses.

Infection and heavy purchasing can still increase stock and price pressure, but their impact has been softened. This should make market price changes feel more controlled and less punishing over time.

Fixes

Added a new infection tutorial that appears when total infection reaches 50% for the first time.
Added guidance for the infection indicator, vaccine crafting choice, and vaccine usage.
Added early-game guidance for the initial TcA infection and TcA vaccine goal.
Improved Supply Market balance so infection and demand pressure are less aggressive.
Updated tutorial visuals for the infection and DNA tutorial flows.
Improved tutorial state handling for new games and save resets.

Closing

This update is mainly focused on making infection management, vaccine crafting, and early-game guidance clearer while making the Supply Market economy feel more balanced.

More tutorial improvements, onboarding updates, and gameplay clarity refinements are still in progress.
