Introduction Real Football 2011 (often abbreviated as RF11) is a mobile soccer simulation game developed and published by Gameloft . Released in late 2010 for Java (J2ME), iOS, and later for Android in early 2011, it was one of the most advanced football games of its time. For Android devices, the game required not only the main application file (.APK) but also separate game data (often called cache or OBB) due to its high-quality 3D graphics, team rosters, stadiums, and sound files.
