Tom Clancy's Rainbow Six: Rogue Spear is a 1999 tactical first-person shooter video game developed and published by Red Storm Entertainment. It is the second installment in the Rainbow Six series and the last entry published by Red Storm before its acquisition by Ubisoft in 2000. The game's plot follows the international counterterrorist organization Rainbow as they investigate the potential acquisition of nuclear weapons by terrorists. Rogue Spear is based on the same game engine and features gameplay and presentation similar to that of the original Rainbow Six. Rogue Spear focuses on realism, planning, strategy and teamwork. Tom Clancy's Rainbow Six: Rogue Spear was released for Microsoft Windows on August 31, 1999, with versions for the Mac OS (2000), Dreamcast (2000), PlayStation (2001), and Game Boy Advance (2002) released later. A PlayStation 2 port was also announced at the time, but it was later canceled. Rogue Spear's engine was later used for the 2003 South Korea-only spinoff Rainbow Six: Take-Down – Missions in Korea. Plot In 2001, Rainbow, a secret international counterterrorist organization led by John Clark, handles a spike in international terrorist attacks, including a hostage situation at the Metropolitan Museum of Art in New York City, an attempted tanker bombing in the Sea of Japan, an aircraft hijacking in Brussels, the attempted deployment of a nerve agent in Oman's water supply, the capture of NATO officials in Kosovo, and a Neo-Nazi group's takeover of a television studio in London. Elsewhere, the former Eastern Bloc has fallen into economic and political disarray since the dissolution of the Soviet Union a decade prior, with conflict and terrorism increasing as money and necessities become scarce. The Russian mafia takes advantage of the turmoil, buying surplus military equipment from the impoverished Russian Armed Forces. Investigating the Oman nerve agent, Rainbow, assisted by an anonymous informant, sources it to anti-Western oil baron Samed Vezirzade. Surveillance of Vezirzade leads Rainbow to an illegal arms deal in Russia between a Russian military unit and Russian mobsters connected to arms dealer Maxim Kutkin and Moscow kingpin Lukyan Barsukov. Rainbow is deployed to interrupt the deal and recovers weapons-grade plutonium, the rest of which they seize from a Russian Navy facility; the Russian colonel in charge of the facility admits he sold Kutkin plutonium multiple times prior, and Rainbow fears Kutkin may be building nuclear weapons. Rainbow hides surveillance devices in Vezirzade's mansion and Kutkin's private spa,
