Security & authenticity
Security rating: Warning
Signing certificate
- Certificate with Google's generic name Google Play App Signing gives the keys it manages this name, but anyone can put it in a certificate, so this alone proves nothing.
- Same certificate as the 6 other versions checked
Store checks
- Developer signature check failed Apr 1, 2026
Scans come from the source store; the certificate comparisons are AAPKs's own, made from the files' published signatures (6 other versions compared). AAPKs doesn't scan files itself.
How to install Mech Arena on Android 6.0+
You'll need about 546 MB of free space.
- Download the APK — tap Download APK above (273 MB). Chrome shows “File might be harmful” for every APK file; choose Download anyway only if you trust this file.
- Open the file — tap the download notification, or open Files › Downloads and tap com-plarium-mechlegion-1038502-72841745-41b8519345048e58408970e47104e341.apk.
- Allow the install (first time only) — Android 8 and later asks for permission the first time an app opens an APK: tap Settings in the prompt, turn on Allow from this source, then go back. Manual path: Settings › Apps › Special app access › Install unknown apps (on Samsung: Settings › Apps › ⋮ › Special access). On Android 7 and older: Settings › Security › Unknown sources.
- Check the file (optional) — the MD5 of the downloaded file should be 41b8519345048e58408970e47104e341. If it differs, the file is damaged or was changed: delete it and download again.
- Tap Install — Android asks “Do you want to install this app?”. The source store flagged this file with a security warning; we recommend not installing it. If Play Protect blocks it, tap Cancel. If an earlier version is installed, this one only installs as an update when it is signed with the same certificate (SHA-1 shown above).
- Open Mech Arena — tap Open on the install screen, or find it in your app drawer.
Common install problems
- “App not installed” — a version signed with a different certificate, or a newer version, is already installed (Android doesn't allow downgrades). Uninstall it first; back up your data, because uninstalling deletes it.
- “There was a problem parsing the package” — the file is incomplete, or your Android is too old (this version needs Android 6.0+). Download it again, or pick an older version.
- “App not compatible with your device” — this build contains native code for ARM 32-bit, ARM 64-bit only. Devices with other processors can't install it.
- Blocked by Play Protect — Play Protect checks apps from outside the Play Store. Only continue if you trust the source; for this file we recommend not to.
