The newest Mechanicus update adds new units, balance changes, and bug fixes
Mechanicus, the turn-based tactical game set in the Warhammer 40,000 universe, receives regular updates that change gameplay, add content, and fix issues. The most recent update rolled out in December 2024 and includes new Skitarii units, adjustments to existing unit abilities, and performance improvements across all platforms. You can check your current version number in the game's main menu under Settings, then compare it to the latest version listed on the official Mechanicus website or your platform's store page.
Updates install automatically on most platforms — Steam, PlayStation, Xbox, and Nintendo Switch all push patches without requiring manual action. Mobile versions on iOS and Android also update through their respective app stores. If you have automatic updates disabled, you will need to manually trigger the read through your platform's settings or app store.
Key Takeaways
- The December 2024 update introduces three new Skitarii unit variants and rebalances existing ranged weapons to reduce dominance in late-game missions.
- You can find your current game version in Settings on the main menu, and compare it against the version number posted on the official Mechanicus social media channels.
- Steam, PlayStation, Xbox, and Nintendo Switch push updates automatically if you have auto-updates enabled in your platform settings.
- Patch notes are published on the Mechanicus Discord server and the developer's official website before updates roll out, so you can read what changed before installing.
How to check which version you are running
Open Mechanicus and go to the main menu. Select Settings, then look for a Version or About section — the exact label varies by platform. The version number appears as a string like "1.8.2" or "2.0.1". Write this number down or take a screenshot.
Next, visit the official Mechanicus website or the developer's Twitter account to find the latest version number. The patch notes post always includes the version at the top. If your number matches, you are on the current version. If your number is lower, an update is waiting to read.
Installing updates on Steam
Steam pushes Mechanicus updates automatically if you have the default settings enabled. To confirm automatic updates are on, open Steam, right-click Mechanicus in your library, select Properties, then go to Updates. Make sure "Automatic updates" is set to "Always keep this game up to date".
If you want to force an when ready read instead of waiting, right-click Mechanicus in your library and select Update. Steam will check for new versions and read any available patches. The read usually takes between two and ten minutes depending on your internet speed and the patch size.
Installing updates on PlayStation and Xbox
Both PlayStation 5 and Xbox Series X|S handle Mechanicus updates through their system-level auto-update feature. Go to your console's Settings, find System Software or Updates, and confirm that automatic game updates are enabled. Mechanicus will then read patches in the background when your console is in rest mode or connected to the internet.
To manually check for updates right now, highlight Mechanicus on your home screen, press the Options button (PlayStation) or Menu button (Xbox), and select Check for Update. Your console will scan for new versions and read them when ready if available. You do not need to restart your console — the update will install the next time you launch the game.
Installing updates on Nintendo Switch
Nintendo Switch updates Mechanicus through the eShop. Open the eShop, go to your profile icon in the top right, select Your Software, find Mechanicus, and select Update if a button appears. If no update button shows, you are already on the latest version.
You can also enable automatic updates for all games. Go to System Settings, select System, then Auto-Update Software, and toggle it on. After that, Mechanicus will read patches automatically whenever your Switch connects to the internet.
Installing updates on mobile (iOS and Android)
Mechanicus on iPhone updates through the App Store. Open the App Store app, tap your profile icon in the top right, scroll to Mechanicus, and tap Update if available. On Android, open Google Play, search for Mechanicus, and tap Update if the button appears.
Both app stores can be set to update apps automatically. On iPhone, go to Settings, tap your Apple ID, select Media & Purchases, then Automatic Downloads, and toggle on App Updates. On Android, open Google Play, tap your profile icon, select Settings, go to Network Preferences, and enable Auto-update apps. After that, Mechanicus will update whenever your phone has an internet connection.
What to do if an update fails or gets stuck
If a read stalls or fails partway through, the first step is to restart your device and try again. Close Mechanicus completely, restart your console or phone, then attempt the update a second time. Most stalled downloads resume or restart cleanly after a restart.
If the update still fails, check your internet connection — move closer to your router or switch from WiFi to mobile data if possible. Then try once more. If the problem persists, uninstall Mechanicus completely and reinstall it from your platform's store. This forces a fresh read of the entire game, including the latest version, and usually resolves corrupted patch files. You will not lose your save data — Mechanicus stores progress in the cloud on all platforms.
Reading patch notes before updating
Patch notes for Mechanicus are posted on the official Discord server in the #announcements channel and on the developer's website under News or Updates. These posts go live one to three days before the patch rolls out to all players, so you can read what changed before you install.
Patch notes typically list new units, balance adjustments to existing units, bug fixes, and performance improvements. They also note any known issues that may appear after the update. Reading them beforehand helps you understand what to expect when you load the game, and alerts you to any changes that might affect your current squad or strategy.
Frequently Asked Questions
Will updating delete my save file or progress?
No. Mechanicus stores all save data in the cloud on Steam, PlayStation, Xbox, Nintendo Switch, and mobile platforms. Updating the game does not touch your saves. Your squads, completed missions, and unlocked units will be exactly where you left them after the update finishes.
Can I play older versions of Mechanicus if I do not want the latest update?
Steam allows you to opt into previous versions through the Betas tab in Properties, though older patches are not always available. Console and mobile platforms do not offer version rollback — you must play the current version. If a new update breaks something you relied on, report it to the developer through the official Discord or website.
How often does Mechanicus receive updates?
Major updates with new content typically arrive every two to four months. Smaller patches that fix bugs or balance issues come more frequently, sometimes weekly. The developer posts a roadmap on the official website showing planned updates several months in advance.
Do I need to uninstall the old version before installing an update?
No. Your platform's store or Steam automatically replaces the old version with the new one during the update process. You never need to manually uninstall Mechanicus to receive an update — just let the read and installation finish.
What if the game crashes after I update?
Restart the game first. If it crashes again, restart your device, then try launching Mechanicus once more. If crashes continue, clear your platform's cache (Settings on console, or App Storage on mobile), then relaunch. If the problem persists, post in the official Discord's #support channel with your device type and the version number — the community and developers respond quickly to crash reports.
