You play as Alex D. in a gameworld 15-20 years after the first game (Around 2070 A.D.)
Alex grew up in Chicago and is training at the Tarsus Academy there. Tarsus is a new organization
that apparently has powerful enemies, as the first event in the game is a terrorist attack on the Academy.
The nanite detonator used in the terrorist attack completely destroys Chicago, forcing the survivors
(including Alex) to flee to the Seattle headquarters. As if that wasn’t enough, the headquarters are attacked soon thereafter.
In the midst of this turmoil, it’s your job to figure out who to trust by uncovering their secrets.
Factions include the aforementioned Tarsus Academy as well as these:
The Order
A unified world religion. Headed by the shadowy "Her Holiness," the Order can be seen as a disjointed
mish-mash of every religion known to man, or a bunch of low-life terrorist tree-huggers,
or an inspired amalgamation that brings true balance to one's soul. It largely depends on who you're talking to.
World Trade Organization A global trade syndicate run by Chad Dumier, formerly of the terrorist group, Silhouette.
The Omar A secret network of merchants seeking to make a hefty profit on illegal goods
such as blackmarket biomods. Although they aren't necessarily interested in politics,
they are still a force that must be taken into consideration when making decisions.
Templars Bet you thought Manderley killed them all and stole their gold. Well, they’re back! And they have a real grudge against biomods.
You will find out that these factions are founded on what took place in DX. In IW,
factions are always vying for your loyalty. At first, it’s only two factions,
and then more start taking an interest in you. Each faction has a parallel goal
in each mission, and often you will have to choose which goal to complete to show
loyalty to one and only one faction. Unlike in the first game, you have complete
control over which faction you fight for and what you do.
