Deus Ex: Invisible War

Twenty years have passed after the events described in Deus Ex. The actions of JC Denton have eventually led to a period of economic depression, known as "The Collapse". The world is on the brink of chaos after the dismantling of the mighty biotech corporations, and multiple religious and political groups lust after power.

The city of Chicago is destroyed in a devastating energy blast by unknown terrorists. Two trainees of the Tarsus Academy, Alex D and Billie Adams, are evacuated to another Tarsus-controlled facility in Seattle. Shortly thereafter the facility is attacked by members of a religious organization called the Order. Billie admits that she has been collaborating with them, implying that Tarsus may be involved in a conspiracy. It is now up to Alex to find his or her place in the new world, and ultimately shape its fate.

Deus Ex: Invisible War is a first-person shooter that retains many gameplay elements of its predecessor, such as conversations with characters, inventory management, exploration, and mixing various gameplay styles during missions. As in the original game, the style of play helps shape the game as it progresses, from how characters interact with the protagonist to the types of situations encountered. Each potential conflict can be resolved in a number of ways, through peaceful means or through violence, using stealth or a show of force. Hacking computer terminals and unlocking doors with special tools are prominently featured.

Weapons can be modified in a variety of ways, e.g. increasing their rate of fire, silencing the shots, allowing the weapon to shoot through glass, etc. Characters can once again outfit their bodies with an array of biotech parts, some of which include the ability to see through walls, disappear from radar, regenerate from critical hits, or jump forty feet in the air. Unlike the previous installment, there are no true role-playing elements in the game. The player must search for biotech canisters to install and upgrade biomods; however, no experience points are awarded for either completing missions or dealing with enemies. Inventory management has been simplified as well.

The sequel places more emphasis on decisions and different approaches to missions. From the beginning of the game the player has the freedom of performing missions for organizations and people of his or her choice. Like in the first game, several endings can be reached depending on the player's decisions.
