You are in control of X-COM: an organization formed by the world's governments to fight the ever-increasing alien menace.
  • 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.


    • Supported OS: Microsoft® 2000/XP/Vista®
    • Processor: 80386 processor or better
    • Memory: 4Mb RAM

In Memory of the Dujardin Brothers

On June 13, 1999, Squaddie Henri Dujardin, age 32, and Squaddie Bernard Dujardin, age 38, were killed in action during the defense of Berlin, Germany. Many civilians became chryssalids within hours, and upon the arrival of X-squad 3, the city was overrun. The Dujardin Brothers were the first out of their Skyranger and began their mission with fervor. Captian Leonid Torban, their comanding officer, was very fond of the two, "Bernard could hit a muton from 15 tiles away and never miss! Henri, well, I guess he was good with grenades? He was the only one to not kill his own squadmates with explosives".

Soon, however, the two were separated from the rest of their squad due to a cyberdisk pinning them in a small building. Nearby chryssalids soon took advantage of the situation. The brothers made a final, valiant last stand inside the house. Henri set up multiple explosive traps at the entrances to the building and Bernard provided covering fire from the second floor. It seemed the Dujardins would make it, until one fatal mistake.

The cyberdisk was destroyed by fellow squadmates, but it exploded, causing a breach in the walls of their stronghold. A loan chryssalid was able to move into the building undetected, and while Henri had his back turned, the chryssalid impregnated Henri. He became a shambling form of his former self, his mind devoured by the chyrssalid's poison. Bernard, sensing this was his final turn, chose to sacrific himself for his team. He placed a number of high explosives inside the room he was baricaded in.

The only remainder of that building was a single 1x1 wall. Bernard had managed to eliminate 5 chryssalids as well as his former turned brother. Unfortunately, there was no body to recover. Berlin was saved, but at a high cost. Hundreds of civilians lost, 5 agents lay dead, and one turned in to an alien. The victory was sour.

Bernard was promoted to the rank of captian and Henri to sergent upon their team's return to their HQ somewhere in the apparently unimportant part of Europe.

In the end, that 1x1 wall was made into a memorial, the Dujardin Memorial. It lists all of the fallen agents of the campagin, with Henri's and Bernard's names at the top.

A new warcry has been established by the agents of Xcom: Remember Berlin!

10/10 would relive again

I do own the new xcom enemy unkown and within, and i must say even though they are both really challenging and enjoyable, they don't compare to the original.

X-COM: UFO Defense has an tense feeling, like everything could go wrong at any moment, something thats present in the new one but not as strong. I swear while doing missions, my hands shake, especially if i've grown attached to a character, who could die at any moment.

The game gets difficult fast, any free time you have should be spent preparing for battle.

-tense music makes the missions scary
-whenever you lose a soldier that you took the time to name, it hits you right in the feels
-aliens arn't pushovers, they will mess you up
-addicting, I always have to get my fix, that only the original can provide

-I wish i could choose my starting base layout, i always have to move stuff around
-black characters apear white on the battlefield, get hard to keep track of good people
-can't undo actions on the battlefield, somehow this makes he game more tense
-knee high walls make the worst cover, and you always have to walk around them leaving you open to alien fire

Observations and tips
-civilians are stupid as hell, and they always run into the aliens
-alien in corn field = death
-never stand next to a window, you will die
-never pull the pin on a gernade unless you have enough action points to throw it
-first soldier that steps off of the skyranger always dies, choose wisely
-don't get rid of any weak soldiers, use them as meat sheilds for your better soldiers
-DO NOT GROUP YOUR SOLDIERS TOGETHER, aliens have super gernades that will kill all of them
-always have a few worthless soldier on your team to look for aliens, or take gun fire

I would recommend this game to any person who loves turn based, squad management games.

Full disclosure 1: yes, I played the game back when it first came out. So one CAN accuse me of a nostalgia bomb. But I am not reviewing X-com UFO defense from my memory of playing it 15 or so years ago, I am reviewing based on recent play throughs. And it still has all the charm that it had from the start.

Full Disclosure 2: I played the Vanilla steam version for a while, then noticed comments on something calld OpenXCom. (easily found on the net). It's a free, extensive overhaul with many mod choices built in. Very easy to set up; you do need to have a vaniilla version (steam version works for disc required, and it is pretty cheap). Some of the many choices are PSI on/off; improved H. Lasers, choices for setting up your first base rather than accepting the default, and so on. Highly recommended.

Ok, the actual review. It is one of my favorite games of all time (not judging it in its release time frame, but CURRENTLY). The graphics are last century, iti is true. But the gameplay is +++++. It is tough; there is a lot to figure out, and things never seem to happen in an orderly fashion. Sometimes you just have to give up a mission; sometimes you just have to give up a game. The aliens like to win, LoL. It's a lot of fun to grind through a mission successfully, but there are no guarantees.

One of my criteria for a top notch game is whether it provides not only fun, dangerous stuff to do throughout, but once in a while something unexpected happens that blows me away. Like when I found out if I through a grenade on a roof, that it could bounce, and if it bounced into an alley it would fall to the ground, and if there was a hidden alien there you would hear a muffled explosion and then....the alien death cry you hardly expected. First time that happened I had to save and quit for a while...I was laughing too hard.

If you like challenges, tactics, and turn-based games, this is a must try out. Good luck, andI I hope you can stop those monsters!

When you open a door and see 4 aliens standing in front of you, looking at you- guns in hand...
then you know it's time to run. But do you dare to turn your back on them?
Amazing game, as far as turned based strategy games go. 10/10

The one that started it all. Turn-based tactical goodness.

Also, the game hates you. Passionately. 10/10 would get ♥♥♥ kicked again.

One of the timeless classics and a milestone in the history of video games. The graphics may have aged but the gameplay did not - it remains as challenging frustrating but rewarding game as it was when I played it for the first time (around 1995).
Funny how this game inspired so many others none of them actually surpassing this one...

Still one of the greatest games of all time. Deep turn based tactics and an enthralling overworld strategy combined that have still never been outdown. They pull as much character and feel out of the graphics and sound as humanly possible for the technology at the time; if you can forgive the graphics, the aethetic is amazing. Can also check out the "openXcom" remake for what's essentially the same game with some fixes and slightly revamped UI.

This game does have learning curve, but there's no other game out there that can really pull you in and make you feel like you really are the last hope of humanity. If you fail, life as we know it is over.

Fantastic game, a real challenge for even the most hardcore strategy gamers. If you like your soldiers being killed by aliens, turned into zombies and when those zombies are killed, more aliens hatching out of them, then you'll love this game!

Easily a classic and one of the best TBS games of all time, I still remember playing the demo on an old 3.5" diskette.
A must have for any XCOM or turn-based strategy (in general) fan.
While I enjoyed Enemy Unknown, in my mind, it is a watered down (though polished) version of this classic.

Don't let the dated graphics sway you, the gameplay and atmosphere are top notch.
They just don't make em like they used too...I must be getting old :/

Hands down THE best strategy game of all time. So tense, layered, emotional and nerve-wrackingly brilliant that I dedicated half my Steam username to honouring X-com and my many, many, many brave fallen soldiers. RIP chaps and chapesses, sorry I couldn't save you all!

You know, just when you think you can play an old game you used to play..and figure wow, I can't do this anymore! But remember games like this was the really good in its time of birth. Great collectors piece.

It is a great game if it's still enjoyable 20+ years after its release. A lot of creativity and effort has gone into putting this game together. What makes this great is not some specific aspect but the whole thing. The main part, the tactical fights are well done, not only the surroundings are dynamic, e.g. buildings literally get damaged by bullets and explosions, but there are nice variety of missions; from desert and forests to protecting civilians in urban areas. Next to fighting and gunning down UFOs you actually get to micro-manage pretty much the whole global operations of the X-COM: from building and maintaining bases and aircraft down to individual soldiers and equipment. You hire scientists to research the extra-terrestrial stuff you loot from the missions, and engineers to build better weaponry and armor as the research progresses. The UFO and space alien stuff is just neatly packaged into this game; it serves the game and drives the story. Graphics are of course outdated by today's standards but don't let that ruin the game for you, pretty much everything else holds up well. I think it's very fun and rewarding game, but complexity and difficulty of managing so many things may be too much for someone.

This is it. The game. There is no "genre" for TBS. There is also no base-building genre. No, this is the only game of those genres in existence. Don't look it up; just trust me, and throw all your money at the screen in the name of Julian Gollop.
XCOM: UFO Defense (previously known as UFO: Enemy Unknown before the 2012 reboot stole its name-- why not come up with a new name, was it really necessary to steal the old name?) is, as I mentioned, THE turn based strategy game. It's suffered from aging mechanics and the limited capabilities of early Windows and late DOS platforms, but other than that has remained intact only because few have attempted to replicate it, and even fewer have succeeded.

This is NOT going to be an easy game to play. Let me just get that out of the way. Your troops WILL die. You will ♥♥♥♥ up. And that's okay; that's XCOM. Unlike XCOM 2012, there's no dicerolling, no RNG hitscan. Every bullet is precisely calculated to do damage to the target it hits-- with that meaning you.

In this title, there is no shame in going through the first pages of the manual your disc came with-- what, no disc? Don't worry, it's nicely packed in PDF form if you go to the game's steamapps files. The game itself offers no handholding across the street, and you'll have to watch it closely to make sure it doesn't throw you under a bus.

Play on Beginner if you need to, Challenging if you have the nerve, any higher and you shouldn't cry when your inevitable loss comes around-- you earned it yourself. And that pretty much sums up this game.

Unlike 2012's reboot, everything you do in this game is done by you. You have more control over XCOM and more in-depth micromanagement of your arsenal and supplies. You won't have multiple abductions at once, you have a constant view of the whole world, you can have multiple skyrangers, and you can establish multiple bases. Micromanage your arsenal and supplies, build the square 6x6 grid that is your base, and kiss the ♥♥♥ of the council enough to survive.
It's a no-brainer whether the average strategy gamer will want this or not-- give it a shot, you'll probably like it once you figure out what the shiny red and green interface buttons and knobs do. The question is...
-Will you buy it alone, or do you like suffering enough to continue on to Terror from the Deep and the legendary Crawler Carrier missions?
-Maybe you'll continue even farther (or be rational and skip TftD), and defend a smaller-scale urban area from an alien assault in XCOM Apocalypse?
-Or maybe you'll just buy the $15 XCOM Complete Pack and play through all three strategy games, a space-combat/base management hybrid in SPACE, and... some ♥♥♥♥♥♥ Unreal Engine 1 game we all deny the existence of!
In other words, despite all the bugs, poorly aged mechanics, and clunky DOS interface, plus the use of DOSBOX, I absolutely recommend this game with an 8/10 (9/10 if it weren't a messy DOSBOX port). With OpenXCom, go on and raise that ♥♥♥♥ to 10!

Games you may also enjoy:
Nothing. XCOM UFO Defense is the only game you'll ever need. Okay, fine, I'll give you some recommendations...
Mod Showcase: OpenXCom
A complete overhaul of the original game that fixes some of the clunky interface and removes the need for DOSBOX, plus gives us resolution options and optional improvements such as tweaked bulletcam and better sprites, as well as mutators. Definitely worth checking out, since the changes to AI behavior it makes are optional.
Recommended Purchase Method: XCOM Complete Pack
Buy all three classic XCOM games, get Interceptor for free! We don't talk about Enforcer.

This game is a legacy. X-COM revolutionized turn-based strategy gaming and to this day, though the graphics may have aged, the gameplay does not get old. It's a bit difficult to get into because of a few annoying design flaws such as the fact that there's no in-game explanation of what all those battlescape buttons actually DO, but once you've figured it out this is a great game that every strategy fan should play.

As for the 2012 XCOM game, although that's an amazing game, it's also quite different from this one. Get them both because they're both amazing but in rather different ways. In fact, get the entire series. There's a bundle of the old XCOM series which includes X-COM: UFO Defense, X-COM: Terror from the Deep, and X-Com: Apocalypse, as well as the spinoffs Enforcer and Interceptor which aren't strategy games, per se, and don't work on my computer, but the cheapness of the bundle makes up for that.
