organization led by Bastian Vanderwaal, steals "Legion", a nanite aerosol bioweapon that causes massive hemorrhaging and has a 100% fatality rate. Later, the GLF attacks the Scottish Parliament Building, and Alpha saves the hostages and captures some of the terrorists. The captured terrorists reveal a GLF cell's training facility under a distillery in Olivet, which Alpha raids to capture cell leader Derek Mergen; however, Mergen is shot by his own men in an attempt to silence him, but he survives and is hospitalized. After Alpha defends the hospital from a GLF onslaught, Mergen tells Clark the GLF is planning something, though he does not explain what. Raiding another GLF facility in Paris, Rainbow learns a GLF cell will conduct an arms deal for the plan at the Port of Calais. Rainbow and the GIGN ambush the deal, but the GLF, expecting their presence, hijacks a ferry and rigs it with explosives to deter pursuit; Alpha, assisted by Rainbow sniper Dieter Weber, is able to board the ferry and defeat them without incident. GLF informant Nicolai Yazhov, a KGB rival from Chavez's CIA career, offers to meet with Rainbow in Marseille, but the meeting is an ambush and Yazhov flees. Chavez pursues and captures Yazhov, and Alpha saves him from GLF hitmen; Yazhov claims he was forced to organize the ambush, and points Rainbow to Algerian arms dealer Faisal Amidan. Alpha infiltrates Amidan's heavily-guarded compound in Algeria, where they identify Vanderwaal. However, while exfiltrating, Weber is captured by the GLF. NATO declares him an acceptable loss, but Chavez defies orders and rescues Weber from captivity. Investigating Vanderwaal's Gibraltar estate, Rainbow learns the GLF's plan is to attack the NATO Summit in Barcelona and infect the world leaders present with Legion in a live broadcast. The GLF launches the attack later that day, but Alpha is able to defeat the terrorists and rescue the NATO leaders. Rainbow tracks Vanderwaal to an old castle on Menorca, but Vanderwaal is nowhere to be found. Interrogations reveal Vanderwaal is attempting to leave Menorca, planning to poison a major European city's water supply with Legion. Alpha intercepts them, defeating the remnants of the GLF and killing Vanderwaal, ending the GLF's threat. The plot of the PC version is essentially the same as the console version, the only differences being less missions, a slightly different chronology (such as Amidan being identified earlier), and the antagonists being multiple
