Deus Ex: Invisible War

Deus Ex: Invisible War is a videogame developed by Ion Storm and released in 2003. It is a sequel to Deus Ex and follows the story of Alex D as he uncovers various factions conspiring to control the world. It sports nifty physics, and decent 3D graphics.

Plot elements
The plot of Deus Ex Invisible War, which takes place in 2072 (20 years after the events of the first Deus Ex) assumes that a combination of the three endings of the original Deus Ex had taken place. JC Denton merged with Helios, but destroyed Area 51, triggering the Collapse event. This had paved the way for the Illuminati to seize control of the world through two organizations, the WTO (World Trade Organization) and the Order Church. The former upholds the capitalist ideals of the Illuminati and regulates any activity that conflicts with the free market (non-profit or otherwise). The latter is the exact opposite, utilizing pseudo-religious ideals to combat the capitalist ideals of the WTO.

Also, an AI collective known as the Omar appears periodically in the game.

For much of the earlier stages of the game, the WTO and Order, through their second-in-command (Donna Morgan of the WTO and Lin-May Chen of the Order) order Alex to perform investigations directed at the Tarsus Academy chain, and the activities of the Luddite faction, the Knights Templar, an offshoot of the Order, led by Order Luminon Saman. The Knights Templar were responsible for the destruction of Chicago (targeted at the local Tarsus academy), and Alex, whose home was that very academy, becomes involved with their activities as a result. Alex later meets Saman at the Cairo Order Church in the first Cairo level, along with his former classmate, Billie Adams, who joined the Templars at that point. At the second Cairo level, Saman tries to convince Alex to join them in eradicating biomods.

The ApostleCorp organization, founded by Paul Denton, is later revealed to be behind the Tarsus chain and its experiments on students in terms of biomodification. The purpose of ApostleCorp, revealed by scientist, Dr. Leila Nassif, is to biomodify every human being, bringing about a peaceful "posthuman" civilization. At Trier, Germany, Alex meets Tracer Tong, the leader of the local ApostleCorp facility, who reveals that the organization was founded to fulfil the JC/Helios entity's ideals by creating biomod infusions, special biomods that allow persons to biomods like they would use their regular human abilities, for every person on Earth. One such infusion was tested on Paul, but it wasn't perfected, so Paul's body rejected it violently, so Paul had to be frozen. He also reveals that JC had to be put into stasis, because his merger was unstable. Tong prods Alex to go to Antarctica through a portal at the Black Gate Ruins, which only persons with biomod infusions can access as a precaution. Alex also learns about the Illuminati at Trier from its two leaders, Chad Dumier (WTO leader) and Nicolette DuClare (Order leader).

Eventually, Alex goes to Antarctica to repair JC with his biomod architecture, only to be intercepted by Billie. When Alex finally bests her, he continues and revives JC, who confirms what Tong and Nassif had told him pertaining to ApostleCorp's goals, and he orders Alex to rescue Paul, who had been abducted from ApostleCorp Cairo.

When Alex arrives in Cairo in the second Cairo level to rescue Paul, he is confronted with three options, give his blood to the Templars to end biomodification, kill Paul by cutting off his life support (per orders from the Illuminati) or save Paul as JC wanted. When Alex goes to Liberty Island in the final mission, he learns of the global communications protocol used by Majestic-12 in the first game to control global networks, the Aquinas Protocol (stored in the old UNATCO HQ bunker). Each faction wants Alex to upload the protocol to them for their own use. Whoever he uploads it to will be his affiliation in the endgame, and will trigger one of three endings. If he uploads to no-one, and instead kills all the leaders, he will side with the Omar, triggering a fourth "Omar" ending. If the player carries a flag in the HQ bunker to the bathroom, and flush the toilet, he/she will be instantly transported to an Easter-egg ending, where every major character is seen dancing at Club Vox.

Endings
JC/Helios ending: Alex merges his biomods with JC/Helios and it sends the biomods to people across the world from the top of liberty island.

The Templars ending: biomodification is wiped from the face of the earth and JC and Paul are both killed and the templars rule the world with their religious beliefs.

The Omar ending: the world is plunged into chaos and war and the omar fight until they rule the world completely.

the illuminati ending: their vision of a perfect world is realised and it becomes a world run by the illuminati as an age of light.

Weapons and Items
There are several new weapons in this game including the Boltcaster (a gun version of the riot prod), concussion prox mine, glass destabiliser, spider bomb and Energy blade, as well as old ones, such as the pistol. There are also five secret weapons, powerful weapons in not-so-obvious locations: the Mag-Rail (an energy projectile weapon and the easiest secret weapon to procure), SMG Widowmaker (a gun powerhouse), Red Greasel Hunter (a projectile weapon specialized for killing Red Greasels), Hellfire Boltcaster (the Boltcaster version of the flamethrower) and Dragon's Tooth Sword.

Multitools still exist, but are more reminiscient of screwdrivers than mobile phones (like in the first game). In this game, Multitools still serve their electronic bypass function, but can also serve as lockpicks. Datacubes, bioelectric cells and medkits also continue to exist in this game.

Biomod canisters are also found in the game. They are very similar to augmentation canisters, but can also upgrade existing biomods, and the biomods' installations are not permanent, and can be replaced at any time by another biomod. Old augmentations, such as Spy Drone, Aggressive Defense System, Cloak, Light and Speed Enhancement continue to exist as biomods, but several new ones, such as Neural Interface, Biotox Attack Drone and Health Leech Drone can be found throughout the game. One biomod infusion can be found with Tracer Tong in Trier.

Creatures and Bots
Greasels, Karkians and Grays (from the first game) are found in this game. A special variety of Greasels, known as Red Greasels, are more aggressive and dangerous than ordinary Greasels. The best bet of defeating Red Greasels is the Red Greasel Hunter, one of the game's five secret weapons. Grays are affiliated with ApostleCorp, and will readily help them when called upon.

Medical bots, repair bots, spider bots and security bots, though different in appearance from the first game, still exist in this game.
