Despite being a community project, CS Portable packed a surprising amount of content into a small file size.

The project was born out of a desire to bring the "old school" shooter experience to smartphones before official ports existed. While Valve eventually released Counter-Strike: Global Offensive (and later CS2) on PC, they never released a native, standalone mobile version of their classic titles. CS Portable fills that void.

A robust offline mode allowed for practice without an internet connection.
