Quake I Android Port! I am not affiliated with the original author of the Play Store app (https://play.google.com/store/apps/details?id=com.n0n3m4.Q4A). But the original author did not create a GitHub repository for this code (the author included the sources in the apk, which you have to root your device to access). The original author may request ownership of this repository and I will gladly give it over.
