New Updates: Toxic Gas Leak & Placement Clarity

Hi miners, 😄

Thank you very much for your continued support, bug reports, and feedback. In this update, we are focusing on machine placement clarity, Toxic Gas Leak event improvements, and better in-game information so players can understand important conditions more easily during production.

Please note that some of the changes in this update can already be experienced in the Demo, while the full experience of these updates will be available once Mineral Mining Simulator launches in Early Access.

We are also happy to officially reveal our Early Access release date: May 14, 2026. Be sure to wishlist Mineral Mining Simulator and stay tuned for the release day.

Here is what we prepared for this week updates.

Main Updates

1. Improved Machine Deploying Display

We updated the machine deploying display to make placement clearer and more comfortable while building your production line.

The changes include:

• Clearer spatial information for input, output, and failed output points, so players can more easily determine whether a machine is properly connected

• A spatial grid below the machine to make grid distance easier to read

• More contrasting directional arrow colors during deployment, so they are easier to see against the machine preview

These changes should help make machine placement more readable, especially in more complex layouts.

2. Toxic Gas Leak Event Behavior Updated for Employees

Based on community feedback and our internal testing, we updated how employees behave when a Toxic Gas Leak Event happens.

The changes include:

• The idle duration for employees affected by toxic gas has been reduced from 10 to 20 seconds to 5 to 7 seconds, so the penalty feels less punishing

• The number of employees affected by toxic gas will now match the number of active Toxic Gas Leak Events

Previously, this behavior used a percentage-based calculation. Now it will directly follow how many toxic gas leak events are currently active.

3. Temporary Mining Spot Display Updated After Toxic Gas Leak

We improved the presentation of Temporary Mining Spots that appear after a Toxic Gas Leak has been neutralized.

The changes include:

• Mining Deposit Remaining information will now be shown, so players know when the temporary mining spot is getting close to depletion

• This information will remain visible until the spot is depleted

• Once the temporary mining spot is depleted, its Survey Level will reset back to the beginning

This reset is intended to keep the system more challenging and meaningful for players.

4. Improved Warnings and Informational Messages

Based on feedback about players not always knowing why certain conditions happen, we updated several warning and information displays.

The changes include:

• Added clearer text information for Storage Machine failed output, explaining that when the storage slots are full, items will go to the failed output line

• Updated the Shipping Depot UI to explain that at least 100 item quantity must be delivered to gain reputation, so players better understand why reputation may not be earned

• Added HUD notifications for machines that are running low on packaging or have empty packaging, so players can prepare replacement supplies in time

• Added spatial icons on packaging-related machines when packaging is low or empty

These updates should make the game communicate important situations more clearly during daily production flow.

Improvements

1. Core Drill Machine Maintenance Balancing

We adjusted the maintenance calculation for the Core Drill Machine so the latest version feels fairer.

2. Tutorial UX Improved

We improved the tutorial display so it
