America's Army is a free First Person Shooter made by the United States Army. Its game play centers around teamwork and objective based scoring. Constantly updated, new versions are released frequently. An overhaul of the game, version 3.0, is expected to be released sometime in 2009.
Since version 2.5, no native Linux clients of America's Army have been released. Playing a version that is not the latest is not recommended as there are few servers using older versions. As of November 1, 2008, the latest version is 2.8.4.
