Apocalypse

Earth has been ravaged by human excess, petty conflict and alien invasion. The world's population has been herded into huge cities, the first of which was Mega Primus.

2084: A Utopia shattered, social collapse and civil unrest reigns in Mega Primus. Fiendish aliens terrorize the city. UFOs swarm through Dimensional Gateways. The city's under siege from an unknown enemy.

Your mission, as X-COM Commander, is to combat alien aggression and uncover their deadly intentions. But Beware! Alien infiltration into the city and its politics could see you under fire from criminal gangs, religious sects, and even the police!

Alien fleets fill the skies, creatures terrorize the city, chaos reigns... Welcome to the war, welcome to the Apocalypse.

Enforcer

The Place: America - early 21st century

The Mission: Eradicate the extraterrestrials

Alien forces have invaded Earth and are terrorizing the population. To combat this sinister threat, a lone X-COM scientist has created the Enforcer, a high-tech fighting machine made of earthly robotics and scavenged alien technology.

Armed with the latest high-powered weapons, the Enforcer is sent into alien hot spots to fight in adrenaline-charged battles that rage on city streets, across rooftops and in the sewers. YOU are the Enforcer.

Powered by the same game engine as Unreal Tournament™, X-COM ENFORCER™ puts you on the front line of an alien attack.

Interceptor

Terror from the Deep

Seeking to take advantage of a weakened Earth, X-COM's deep space foes unexpectedly change strategy and launch a powerful second front against planet Earth.

In the dark depths of vast oceans, long sleeping forces are awakened by reanimation signals sent out across the galactic silence by their interstellar brothers and sisters. Slowly but surely, an army of hibernating alien sea creatures awakens. Your combat now extends to the strange new worlds of the deep where superior alien technologies threaten the very survival of this planet - your planet - Earth.

UFO Defense

• Command deadly close-combat battles:
  Shooting down UFOs is just the beginning: you must then lead a squad of heavily-armed soldiers across different terrains as they investigate the UFO crash site. Tackle the aliens with automatic rifles, rocket launchers, and even tanks in the struggle to retrieve useful technology, weapons or life forms.
• Research and manufacture alien technologies:
  Successful ground assault missions will allow X-COM scientists to analyze alien items. Each new breakthrough brings you a little closer to understanding the technology and culture of the alien races. Once you have sufficient research data on the UFO's superior weapons and crafts, you'll be able to manufacture weapons of equal capability.
• Develop a strategy to save the Earth:
  You must make every crucial decision as you combat the powerful alien forces. But you'll also need to watch the world political situation: governments may be forced into secret pacts with the aliens and then begin to reduce X-COM funding.
