ARMA (stylized as ARMA) is a series of first-person tactical military shooters initially developed for Microsoft Windows. Renowned for its focus on realism and simulation, the series combines large-scale military operations across expansive environments with intense close-quarters combat. The franchise’s debut title was released in 2006, with the latest installment arriving in 2013. Over time, ARMA games have expanded beyond Windows to include versions for Linux, Android, and iOS platforms.
The first game, titled *ARMA: Armed Assault* (known as *ARMA: Combat Operations* in the United States), launched on 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 series’ third installment, *ARMA 3*, is a standalone title for Windows that was officially released on September 12, 2013, powered by the newer Real Virtuality 4 engine. An earlier version of *ARMA 3* was made available to the public through Steam’s Early Access program on March 5, 2013. Between late 2015 and early 2016, *ARMA 3* was also released for Linux and Mac, initially as an earlier version, with plans to update these platforms to match the main Windows version later.
