Star Wars Republic Commando: Triple Zero - the sequel to Star Wars Republic Commando: Hard Contact - is set a year after the battle of Geonosis, and follows the continuing missions of Omega Squad. As the Clone Wars casualties mount, the commandos find themselves deployed on increasingly dangerous missions that take them beyond the battlefield and further into sabotage and intelligence operations in the heart of Separatist territory.

Newly-promoted Jedi Generals Etain Tur-Mukan and Bardan Jusik are also catapulted into front line combat roles and find themselves identifying strongly with the clone soldiers under their command, who turn out to be anything but predictable cannon fodder. Then Omega Squad survives a close brush with disaster to end up in the most potentially dangerous hot spot in the galaxy.
