Before You Download
Two checks prevent nearly every failed setup. Storage first: the ISO alone is about 1.69 GB, and Android needs working room while you move it into place, so keep at least 2.5 GB free before you start. Connection second: put the ISO on Wi-Fi. It is a single large file, a dropped download cannot be resumed by the launcher, and a file even slightly short of its full size fails at launch, not at download.
Phone third, briefly: the launcher needs Android 10.0 or newer. Anything mid-range from the last few years runs the campaign properly.
Installing After the Download
Install the launcher from the APK first. Then open it once so it creates its Black folder, close it, and move the ISO into that folder, or open the launcher again and use Import game to pick the ISO where it already sits. Start the game from the launcher. The homepage carries the same steps with the folder path spelled out and the fixes for the messages players meet most.
Why Download From Here
Two-file games attract broken re-uploads, usually an old launcher paired with a trimmed ISO. This page publishes its checks instead: the launcher package is com.racas.black, the APK measures 22,730,089 bytes, and the ISO measures 1,686,306,816 bytes with its disc structure verified. Our reviewer finished missions using these exact two files on real phones before they were listed. No bundled installers, no extra apps riding along, and no store rating borrowed from a shop the game never appeared in.
