Command And Conquer: 3rd Strike

Command and Conquer: Generals – 3rd Strike is the expansion pack for the 2003 video game Command & Conquer: Generals. Zero Hour added several new abilities and units to each side, and a new mode of play called Generals' Challenge, along with a lot more changes, new features and bug/glitch fixes.

Background
Zero Hour contains 3 new campaigns of five missions each, one for each side, with their chronological order being USA first, Global Liberation Army (GLA) second, and China last. Unlike the previous campaigns, which were noted by Command and Conquer fans for not having full motion video cinematic sequences during mission briefing, the Zero Hour campaigns return to that Command and Conquer tradition, each showing a live-action video of a news reporter of the respective side giving details about the situation and instructions for what to do behind the current mission. The plot behind the Zero Hour campaigns picks up where it left off at the end of the previous campaigns.

United States
The beginning of the US campaign relates to the GLA's success in the previous game. As the GLA moves into Europe, the German goverment attempts to develop resistance against the GLA, but is taken down, as a Scud Storm rains on Munich, killing the entire population. In the 1st mission, the US Army is busy fighting a unknown splinter cell in Texas, going horribly wrong.

In the 2nd mission

GLA
The start of the GLA campaign begins with Dr. Thrax's second in command (it is implied that the player acts as this person) being pursued by the Americans through an unknown city in the Middle East. Despite intense Tomahawk bombardment by the Americans, the General manages to evade the American pursuers and escapes from the area in a plane. With the whereabouts of Dr. Thrax still unknown, the GLA command is in complete disarray resulting in several splinter cells being formed to seize power. One such General, Prince Kassad uses stealth technology to which is vital to the GLA's war effort. Having abandoned the GLA cause, the loyalists in turn attack Kassad's base in Egypt, acquiring the stealth technology and killing Kassad in the process. Now equipped with the new technology, the GLA launches a series of covert operations in the Mediterranean, aimed at destroying the US fleet based there, including the USS Reagan, a powerful super carrier. The GLA remarkably achieves this feat by using a captured Particle Cannon to sink the carrier. Shaken by the decisive victory, rumors begin to spread that the US is unwilling to continue its war against the GLA and will begin pulling troops from its bases in Europe. The GLA seize this chance and land commandos on the US West Coast to steal toxins and US Army equipment from inside America. Jarmen Kell leads the attack, and ultimately succeeds in forcing the bulk of US forces be withdrawn from Europe to defend the homeland. The GLA, once again seizing the chance of a weaker American presence in Europe, launches an assault on US Central Command Base in Stuttgart, capturing Chinese and US bases and using the stolen hardware in the attack. The assault succeeds, and ushers in the period of GLA control over Europe.

China
Angered and embarrassed by the GLA's use of Chinese weaponry in taking Europe, the Chinese respond by deploying nuclear weapons against the terrorists. Survivors of the nuclear attack at Stuttgart prompt the Chinese to remove the GLA threat and liberate Europe in the process. But as the Chinese mobilise in Europe, a massive GLA assault against a nuclear reactor complex near Yencheng almost results in another GLA incursion inside China's borders. Though the reactor's defences were considerably crippled, the attack is ultimately thwarted and the Chinese successfully secured their borders once more. Determined to eradicate the GLA in Europe, the Chinese begin the counter-offensive in Germany, but international opinion of the Chinese will determine how well they will be received, so restraint is placed upon the Chinese to not deploy their nuclear weapons here. The city of Coburg is heavily defended by the GLA, but the Chinese resolve manages to push back the defenders, ultimately wiping out the GLA in the region, as well as allowing European opinion towards the Chinese to skyrocket. After taking serious losses to the Chinese, the GLA begins a mass withdrawal from Europe, but part of the route will pass a PLA base in Halberstadt, which is outfitted to intercept the retreating forces. Having lost almost all of its forces present in Europe, the GLA has but one last stronghold based in Hamburg. The Americans manage to rally enough forces to attack the base, but the GLA ambushes the American base, capturing it and using the US hardware to put a halt to the Chinese juggernaut. The Chinese manage to acquire US technology themselves, and push towards the heavily fortified GLA base. After heavy fighting, resulting in massive casualties on both sides, the Chinese emerge victorious and takes its place as the world's sole superpower. Meanwhile, it is implied that after the war, America, severely weakened by the war and upstaged by China, adopts a policy of isolationism.
