Despite conditions the troopers would remember as hellish, they defeated the Confederacy's droid forces, as well as several wild acklays. The 501st legion also fought in the Battle of Felucia alongside Jedi Knight Aayla Secura. Crucial to the mission, they managed to keep their commander, Jedi Master Ki-Adi-Mundi, unaware of their true purpose. The clones succeeded in pushing back the droid forces, recovering the power crystal, bringing it back to a Republic Gunship, and transporting it away from Mygeeto.

In the Battle of Mygeeto, they were involved in Project Hammertong, a clandestine mission to acquire a power crystal for Chancellor Palpatine, who secretly had plans of constructing a superlaser-armed battlestation. In 19 BBY, the final year of the war, the 501st took part in several battles pivotal in ending the war. Under the orders of Chancellor Palpatine, the 501st would sometimes operate outside of the usual command structure, with detachments of the unit serving at many pivotal campaigns.

In the final days of the war, the 501st was frequently shuttled across the galaxy, often divided into specialized groups to assist other missions. We can control them during the campaign of the game, from the very beginning till their transformation to stormtroopers.

The 501 clone legion is an emblematic clone squad of the game Star Wars: Battlefront II.
