ARMA, stylized as ARMA, is a series of first-person tactical military shooters initially developed for Microsoft Windows. Renowned for its high level of realism and simulation, the series combines large-scale military operations spanning expansive territories with intense close-quarters combat. The franchise’s first installment debuted in 2006, with the latest release arriving in 2013. Over time, subsequent titles have been made available not only on Windows but also on Linux, Android, and iOS platforms.
The inaugural game, titled *ARMA: Armed Assault*—known as *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 U.S. It utilized the Real Virtuality 2 engine. The latest iteration, *ARMA 3*, is a standalone game for Windows that launched on September 12, 2013, powered by the more advanced Real Virtuality 4 engine. It was initially accessible to players via Steam’s Early Access program starting March 5, 2013. Between late 2015 and early 2016, *ARMA 3* was also released in earlier versions for Linux and Mac, with plans to synchronize these releases more closely with the Windows version later on.
