In single-player mode, the player and squadmates do not die when they run out of health, but rather are incapacitated. There are orders to command the squadmates to group up or spread out according to the player's discretion for the situation. The player can order the squad to move to secure any position (wherever the crosshair is pointed), or perform search-and-destroy.

Where possible, the squadmates will usually take their preferred roles (sniper, demolitions and technical). The player can then press the 'use' key to issue an order automatically associated with the object for example, a sealed door may highlight with a synchronized team breach-and-clear command, or a computer console might have a 'slice' (computer hacking) command, while a pile of cargo boxes suitable for a cover position with good vantage may provide a 'take up Sniper/Anti-Armor position' command. Many objects in the game environment will highlight when the crosshair is placed over them. The squadmate order system allows the player general tactical control over the three non-player characters (NPCs) squadmates that round out the four-man commando team. The player acts as squad leader of a squad of four elite troops. The heads-up display (HUD) shows the player character's helmet, with a tactical visor. The game features some gameplay elements that resemble features in other first-person shooters. All information is displayed to the player as though they see what the main character would see.

Republic Commando features a heads-up display themed as a clone trooper's tactical visor. An enhanced port of the game by Aspyr was released for the Nintendo Switch and PlayStation 4 on April 6, 2021. The game was made available on Xbox One via backward compatibility on April 16, 2018. Over the years, the game has come to be considered one of the best Star Wars games ever made, along with gaining a cult following.

Republic Commando received generally favorable reviews at release, with praise directed at its story, characters, and combat, although some criticized the short length and average multiplayer. 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. 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. 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'. It was released for the Xbox and Microsoft Windows in March 2005. Star Wars: Republic Commando is a tactical first-person shooter video game developed and published by LucasArts.
