Tom Clancy's Rainbow Six 3: Raven Shield is a 2003 tactical first-person shooter video game developed by Red Storm Entertainment and published by Ubi Soft for Microsoft Windows and Mac OS X.

The game's plot follows Rainbow, a secret international counterterrorist organization, as they respond to a wave of terrorist attacks threatening South America.

Raven Shield moved toward mainstream first-person shooters like Counter-Strike, adapting various features absent in previous versions.

In 1945, two Ustaše members escape the Independent State of Croatia with Holocaust loot, leaving documents relating to it in a Croatian bank.

Meanwhile, Rainbow, led by John Clark and advised by Kevin Sweeney, responds to a series of neo-fascist terrorist attacks targeting South American oil interests and European financial institutions.

Rainbow's suspicions arise after a series of raids and terrorist attacks on locations across South America connected to Gospić and the smugglers, including an unusually violent attack on a meat-packing facility in Argentina which Gospić owns a minority stake in, and a raid on an import-export company in Brazil storing chemical weapons components.

Rainbow finds a link between Gospić and far-right Argentine presidential candidate Alvaro Gutierrez, who is himself tied to an earlier attack on a Swiss bank.

Dying of liver cancer, Gospić intends to use his vast wealth to resurrect global fascism before he dies: by buying South American oil fields and killing swaths of people across the continent, he would spark an economic crisis, then use his oil profits to raise an international fascist movement and form Greater Croatia under fascist rule.

To bring about the crisis, he plans to attack Festa Junina celebrations in Rio de Janeiro with blister gas.

In 2007, a few months after defeating Gospić and imprisoning Gutierrez, Rainbow responds to a series of consecutive terrorist attacks in Italy.

Instead, players take the role of Rainbow field commander Domingo Chavez and lead a single fireteam consisting of Eddie Price, Louis Loiselle, and Dieter Weber through each of the game's missions.

In 2007, a Rainbow team commanded by Domingo Chavez responds to a series of terrorist attacks with the same demands: an end to Venezuelan oil exports to the United States.

Chavez's team extracts Nusrat Ahmad, an informant who infiltrated multiple terrorist networks; Ahmad informs Clark that Emilio Vargas, Crespo's right-hand man, played a role in an earlier break-in in Boston where financial records relating to the terrorist attacks were stolen from a vault.

After Chavez's team rescues Crespo from an attack while touring Alcatraz Federal Penitentiary, Rainbow learns Vargas is connected to Middle Eastern terrorists.

With an impending attack targeting Mardi Gras celebrations, Chavez's team deploys to New Orleans, locating and defusing a VX-loaded bomb.

Still titled Tom Clancy's Rainbow Six 3, Black Arrow was developed and published by Ubisoft and released for the Xbox on August 3, 2004.

"[55] GameSpot said: "Despite its minor flaws, Raven Shield is still a very impressive addition to the series and a very worthy heir to the Rainbow Six name," and gave the same version an 8.7 out of 10.

While the individual stand-offs and shoot-outs are exhilarating, the removal of any sense of choice or any requirement of tactical thought makes this more of a theme park ride than a military operation.

"[67] Computer Gaming World nominated Raven Shield for their 2003 "Shooter of the Year" award, which ultimately went to Call of Duty.
