The file on this page is idTech4A++ 1.1.0harmattan72lindaiyu, 552 MB, and it installs on Android 7.0 and newer.

We compared the signing certificate of this build with the certificate recorded the first time com.karin.idTech4Amm entered the site, and published both the file's SHA-256 and the certificate's fingerprint above so you can check the download yourself. That comparison says the file was not repackaged by someone else; it is not a review of what the game does.

The manifest declares 12 permissions, including access to the microphone. Android asks you to approve those the first time the game needs them.

Its licence is GPL-3.0-only. We took this build from F-Droid, and the source for this exact version is linked below.

F-Droid, who build and sign this package, flag it: it ships assets (art, sounds, data) that are not free. We pass that on as they recorded it — we have not tested the game ourselves.

We do not show a star rating or an install count for this page: we have no measured figure for either, and a number we cannot source is worth less than an empty field.
