Let's state this now: Counter-Strike is awesome. Many an hour has been wasted passed playing the legendary first-person shooter mod for Half-Life, and now even more hours can be whiled away, as the game has come to Android.
Reddit user /u/a1baomarov has posted in /r/Android detailing how to get Counter-Strike working on Android, which involves moving files over from an existing Steam installation, and installing the Xash3D apk.
95%-100% compability with CS1.6.
This requires Xash3D Android >= 0.17.
Install:
1) Install the APK. Install APK with omp
postfix if you have multi-core device and noomp
if you have single-core device or have problems with omp
version.
