Star Wars: Republic Commando is a tactical first-person shooter video game developed and published by LucasArts. It was released for the Xbox and Microsoft Windows in March 2005. Set in the Star Wars Legends expanded universe, the game revolves around Delta Squad, a special ops unit within the Galactic Republic's Clone Army consisting of four genetically-enhanced clone troopers, referred to as "Clone/Republic Commandos". Throughout the single-player campaign, players assume the role of the squad's leader, RC-1138 ("Boss"), and complete various missions during the Clone Wars. Players can also indirectly control the actions of their squadmates RC-1262 ("Scorch"), RC-1140 ("Fixer"), and RC-1207 ("Sev") by issuing different commands, which allow for certain situations to be approached in multiple ways.
