ARMA (stylized as ARMA) is a series of first-person tactical military shooting games initially launched for Microsoft Windows. Known for its high level of realism and simulation, the series combines large-scale military operations across expansive terrains with intense close-quarters combat. The franchise’s debut was in 2006, with subsequent titles released up to 2013. Over time, ARMA titles have become available on multiple platforms, including Linux, Android, and iOS, in addition to Windows.
The inaugural game, **ARMA: Armed Assault**—also called **ARMA: Combat Operations** in the United States—was released for Windows in November 2006 in the Czech Republic and Germany, February 2007 across Europe, and May 2007 in the United States. It utilized the Real Virtuality 2 engine. The latest installment, **ARMA 3**, is a standalone title released on September 12, 2013, running on the more advanced Real Virtuality 4 engine. The game was first accessible to players via Steam’s Early Access program on March 5, 2013. Between late 2015 and early 2016, ARMA 3 was also released for Linux and Mac platforms, initially as an earlier version, with plans to synchronize these versions with the main Windows release later.
