UFO: Enemy Unknown is published by Micropose in 1993. When we see Micropose as the publisher, we will know that it must be a strategy game, and it indeed is. For sure, any games after 1993 should supports 256-color VGA graphics and digitized sound effects, and UFO is no exception.
UFO is kind of weird strategy when I first play it. We almost don't know what to do, yes almost, not totally don't know what to do. After spending a few minutes with the game, one should have no problem to understand the simple and clean interface and start getting into the game.
The story of X-COM begins in 1998. The initial plot centers around increased reports of UFO sightings. Tales of abduction and terrorism by the unknown aliens become widespread. The nations of the world come to perceive this as a threat and attempt to form their own forces to deal with this, such as Japan's Kiryu-Kai; these forces fail miserably, the Kiryu-Kai not intercepting a single UFO in its five months of operation. On December 11, 1998, representatives from some of the most powerful nations in the world meet in Geneva, Switzerland, to discuss the issue. From this meeting was born the Extraterrestrial Combat Unit—X-COM, which the player takes control of during the course of the game.
On January 1, 1999, X-COM's first base became operational, beginning what would later become known as the First Alien War - a period of time lasting three years. Hundreds of UFOs were intercepted, but forces sent to clean up the crash sites took heavy casualties. Major cities came under attack by the alien forces, and at one point the alien forces even began establishing bases on Earth itself. From these sites, however, valuable knowledge and artifacts were recovered; aliens from several distinct species were captured, studied and eventually interrogated, and their technology was reverse-engineered and put to use by X-COM forces.
In later years, the major breakthrough came—an interrogation revealed the alien's forces were based in Cydonia, on Mars. A heavily armed and armored strike force was sent to Mars in X-COM's Avenger craft (based on alien technology) and managed to destroy the alien brain creature that was apparently responsible for masterminding the entire operation. Shortly before the Cydonia base was destroyed, however, a mysterious transmission was beamed back to Earth from the wreckage of the base, setting the stage for the sequel.
The game starts on January 1, 1999. At first, we need to choose the location of our first base. The main screen that we can see the whole world is called Geoscape. The Geoscape will display X-COM bases and craft, UFOs, alien bases, and sites of alien activity (alien terror sites). We can choose from here to deploy X-COM craft to either patrol designated locations, intercept UFOs, or land at a UFO crash site, landed UFO, alien terror site, alien base, or (when research allows) the alien's main base.
When a craft is sent to land at a UFO crash site, landed UFO, or alien terror site, the game shifts to a tactical phase known as the Battlescape. We command the soldiers against the alien forces in an isometric turn-based battle sequence. One of three outcomes is possible in this phase: either the X-COM forces are eliminated, the alien forces are eliminated, or we choose to withdraw. These battles lead to recovery of alien artifacts which can then be researched and possibly reproduced at the X-COM bases, and can also lead to the recovery of live aliens which may then be assigned as a research project to produce information, possibly leading to new technology.
In conclusion, UFO: Enemy Unknown is a great game, but it requires us to have some patient before really appreciate it. You can download UFO: Enemy Unknown here. The password is included in the package.
