Republic Commando: Hard Contact is the 293 page tie-in novel to the video game, Republic Commando, written by Karen Traviss and is the first Republic Commando novel in the series.
Four Clone Commandos, known as Niner, Darman, Fi, and Atin, are put together to form Omerga Squad after each commando's former squad were killed. Meanwhile, Jedi Padawan Etain Tur-Mukan is hiding out from Qiilura's local warlord, Ghez Hokan, and his militia after witnessing her master's death.
After getting briefed on one of their first assignments, Omega is aware of their new mission; to go to Qiilura and dispose of a clone-killing nanovirus being created by the Separatists and find the head scientist, Dr. Ovolot Qail Uthan. During the misson, however, Darman is injured and is separated from the rest of the squad after salvaging for ship parts that are still intact and slowly makes his way to the rendezvous, killing some of Hokan's men on the way. Concerned by the Republic infiltration, Dr. Uthan commissions Hokan as a Separatist officer and reinforces the area with 100 battle droids and extra officers including the very adept Lieutenant Hurati.
Two Gurlanians, known as Jinart and Valaqil, assists Darman in meeting up with Padawan Tur-Mukan and the two progress to a safehouse. After being sold out by the locals, they move on to rendezvous with the rest of Omega Squad. Darman manages to teach Etain much about combat and leadership, thus starts a bond with the Jedi. Omega Squad then steals many explosive charges and sends a droid to bring the charges to the Neimoidians' communications and destroy it. While taking the explosives Omega also captures a Weequay named Guta-Nay who used to work for Hokan and they learn much about the facility. Free to communicate, Omega Squad, Etain and Jinart meet and prepare their attack on the facility.
Jinart places a detonator in the cellar of Lik Ankkit's mansion where most of the droids are garrisoned, leaving the nanovirus facility with little defense. The squad moves to the facility, where Niner, Fi and Etain set up an E-Web heavy repeating blaster for covering fire. The Darman and Atin storm the heavily armored facility, with the help of Jinart, through the surrounding gdan burrows. They manage to infiltrate the facility successfully and capture Uthan, while Niner and Fi manage to lure Hokan into a trap, where he is then kileld by Etain, where she also takes back her master's sword. Omega Squad regroups and eventually is extracted, while Etain stays on Qiilura with Jedi Master Arligan Zey, primarily to break the attachment she is forming toward Darman.
