Gameplay
As with the originals, X2: The Threat is a Space trading and combat simulator set in the fictional X-Universe, a network of sectors, linked by large space gates. The game features a new graphics engine, a much expanded Universe and 60 different flyable ships, along with a number of new missions available to the player. Unlike the expansion pack, X-Tension, which was almost entirely open-ended, X2: The Threat has a clear background story involving an aggressive alien race known as the Khaak. However, the game remains open-ended and the players are free to pursue the plot at their own pace, if at all.

X2: The Threat was generally well received by critics, with many reviewers praising the graphics and the amount of freedom offered to the player. Common complaints were that X2: The Threat, like its predecessors, was quite slow paced and had a steep learning curve.

Plot
The player takes the role of Julian Gardna, a Pirate and thief. Early on, the Khaak, a hostile alien race, emerge to threaten the X-Universe. The player is asked to undertake a series of missions to uncover their origins, their intentions, and to determine their connection to his missing father. Ultimately, Julian must fight off a massive attack by Khaak, rescuing numerous other characters in the process. Key non-player characters include: Due to the expense of completing the plot, the players are periodically prompted to break away from the plot and increase their resources through trade and other open-ended play.
 * Bret Serra: rogue, pirate and Julian's closest friend;
 * Ban Danna: the head of Argon Secret Service who shares a close relationship with Julian's father dating back to the previous game, X: Beyond the Frontier;
 * Elena Kho, Chief Executive in the influential Terracorp corporation;
 * Saya Kho, daughter of Elena Kho;
 * Kyle Brennan, Julian's father, founder of Terracorp, and protagonist from the previous games.



Open Ended
X2 is set within the X-Universe, which consists of 130 sectors connected by two-way jumpgates. The main area of each sector typically contains several stations and at least one gate. The game is open-ended allowing the player to go where they like, when they like, doing whatever they like; a player is limited only by their in-game status and resources. As such, a driving force of the game is to acquire credits, the universal currency and status.

Using credits, a player can buy wares from a station. These wares may then be flown to another station where they can be sold, ideally for a higher price. However, prices vary - from minute to minute, second to second - depending on demand. The less of a ware there is, the higher its price. As such, the X-Universe has a truly dynamic market-driven economy. A player can capitalize on emergent trends to make vast profits; or as easily, can waste money and time on a bad cargo choice. As a player builds profits they can buy equipment, weapons, ships and stations. The player can acquire an unlimited number of ships and stations, of varying size, shape and function. The player can build factories to produce goods (including weapons and shields) to sell or consume. As the factories require resources, the player can set up ships to perform trading tasks for factories such as buying resources from other stations or selling the product.

The game contains numerous races. Several races feature a full enconomy and can be interacted with by the player through trading, reputation and missions. Several hostile races limit the amount of interactivity to combat. Reputation between the player and the social races can be built up through missions, defending their space, or trading in their space. The reputation affects how these individuals of that races respond to the player, and what kind of missions are offered. A player status is categorized according to 'Mercantile' skill, 'Combat' skill, and a 'Notoriety' ranking for each race.
