About This Game

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

System Requirements

    • Supported OS: Microsoft® 2000/XP/Vista®
    • Processor: 80386 processor or better
    • Memory: 4Mb RAM
    • Sound Cards Supported: AdLib compatible cards, SoundBlaster compatible cards and the Roland LAPC-1.

An absolute classic. I played this game through repeatedly when it was new and came on 3.5" floppy disks. Still a standard against which tactical games are measured. Most fall short, trading depth of gameplay for pretty graphics and cut scenes.
Stop reading reviews. Play X-COM now. You'll thank me.

After seeing many good reviews for this game, I bit the hook and decided to buy it. It was a mistake to assume that "good" back then means "good" now. The game is infuriatingly complex -- just navigating the UI to get your soldiers to shoot is a hassle. Not to mention you have many unnecessary complications that only serve to make the game more infuriating, like TU's, stamina, and base micromanagement (which Firaxis thankfully identified and removed in the reboot). Add a brutal level of difficulty and terrible graphics (I don't really care about graphics, but the sprites are just so low-res it's impossible to see what you're looking at), this game simply isn't worth playing in 2016.

This game is a gem for its time, maybe even one of the best - yet most complex and demanding - pieces ever created on personal computer. Hopefully the presented claim is only little exaggeration. *UFO Defense* gameplay includes multiple aspects such as financial and supply management, base construction planning, research and manufacture organisation, big view world-defense with hypersonic jet planes and later innovative solutions; soldier recruitment and training, as well as turn-based tactical ground combat that the reviewed product pioneered in great extent. Recovery of alien artifacts and technology with their adaptation to Earth-based equipment is crucial to ones development in pursuit of defeating an enemy, whose abilities and ravagery increase with time.

Is this game difficult? Whether it is difficult or easy for someone who already knows how to play it, is one thing - but to learn how to play it on minimum required level, is other thing - and that may be tough; be warned. It is a nostalgia purchase nowadays. User-friendliness is hardly a feature here.

Memories of fine hours dedicated to exploring the world endangered by alien invasion - and its only shield, the international X-COM force - brought me back to this product. I am still under impression of its uniqueness. For present day, yet, this DosBox version - that STEAM claims to be Windows-compatible - is far from working acceptably. Five euro/dollars for a program older than twenty years is robbery considering the current standards. If you are going to buy *UFO Defense*, do it only for the sake of *OpenXcom* - a fan-made and well done upgrade that greatly enchances the playability of the game, next to optimizing it for modern systems. *OpenXcom* requires the original *UFO Defense* data. Know, yet, that this data are remote files that ought to be available for free already.

I truly admire *UFO Defense*, as well as impressive input that the fandom had into making it so much better experience, therefore I need to be fair with what we get on STEAM at the moment for the price of five euro/dollars: thumbs down. DosBox version is out of play.

Ok, i'm sure i'm going to get alot of flak for this but, I just started the game, and I feel that it is unplayable. I have no clue what is going on, there are tons of buttons and I have yet to find something that explains what to do. You get thrown right into the game with no idea of how anything works.

(Don't let those 12.3 DOS Box hours Fool you, I have over 600 hours in UFOextender and OpenXCOM.)

X-Com: UFO Defense is a Retro classic that has still stood the test of time. I picked it up in 2013, with no prior experience of Strategy games WHAT SO EVER. While most people find the ancient, convoluted 90s interface... well, ancient and convoluted, I some how learned the game without even cracking open the instruction manual (Word of advice. Crack open the instruction manual. You will need it if you don't figure out the interface in 5 minutes like I somehow managed.) Despite all this, X-com is a game that I always find myself coming back to... here's why.

Pros:
-Procedurally generated maps means you will NEVER play the same battle twice.
-The balance between the tactical and geoscape is one of my favorite parts of the game. Both would have been a solid game individually by themselves, but the combination of the two makes X-Com one of the greatest strategy games out there.
- THE FREAKING INTRO. *Jumps out of skyranger blasting mutons with auto rifles to epic bit rock* (Note: DO NOT try to use Auto rifles against Mutons)
- Random Generation for your Soldiers as well keeps the game fresh.
- Challenging. This game will make you FEEL like you're defending the earth from vastly superior aliens, making victory that much sweeter.
- The Art style: Campy 90s Sci-Fi at its best
- The Music: John Broomhall has created one of my favorite game OST since Ace Combat 04


Cons:
- Outdated Nineties interface: The Battlescape can be incredibly confusing to new comers.
- Psionic Line of Fire: Download a mod for this, because Aliens spamming mind control when they can't even see you is BS.
- Heavy Lasers / Laser Cannons kinda suck. Could have used more balancing in the weaponry department. (There are also mods for this. Download them)
- ♥♥♥♥ING TURN ONE ALIEN GRENADES IN THE SKYRANGER YAGAHA KSA KHLSADHKASKDASD
(I think there's actually a mod that disables grenades until turn 3 for both sides. So you can actually get your people spread out.)
- Ammo micromanagement is incredibly annoying

Rating?

10/10, Arguably one of the greatest PC games ever created. Just, for the love of god, use openXcom for modern systems.

I spent more than a half year from my teenage childhood to save the Earth from sectoids, ethereals, mutons and many kind of different alien invaders. Well, it worth the time because this games was far the best and I'd say even better than it's Firaxis remake which is great also. Well about the Earth and humankind.... I'm not sure it was worth for saving but know it's 2016 and it seems I fulfilled my mission.

September 15th, 1999.
We are fighting a losing battle.
Mankind's numbers dwindle by the day, while the amount of xenos on our planet only grows.
UFO sightings are in record numbers.
Alien craft are landing on people's lawns and there's barely anything we can do to intercept them.
Every skirmish means another Avenger full of corpses comes back to base.
The survivors are shaken beyond belief.
Every month Chryssalids devour another city.
The much-feared Mutons and Ethereals are showing up in record numbers.

There is only one hope for our race: The Red Planet.
The alien mastermind lurks deep beneath the ancient city of Cydonia.
There is nothing more to be learnt on Earth.
There are no more battles to be fought on native soil.
Cydonia or Bust.

Even if we win, our futures will be forever changed. Mankind may forever live in the shadow of the alien. Or worse-- the shadow of itself, augmented by alien technology.

Sic Transit Gloria Mundi.

This is the ultimate stratagy game, with actually challenging AI, long term advancements, and a very good plot.

You are X-Com, and anti-alien combat group funded to protect humanity, you must crash UFOs, attack landed cruisers, defened cities from terror groups, and stop aliens from alling with the nations.

You must research and manufactor armor, alien weapons, new tanks, ships, perform autopsies, and discover the home base of the menace,

I'm 46. I've played Xcom EU/EW for awhile But i'm getting my ♥♥♥♥ kicked all the time. Seems i'm not that good at playing them.

So the other day and with all the hype around Xcom 2 getting my attension I bought X-COM: UFO Defense AKA XCOM: Enemy Unknown (1994) as I had £1.20 on my account, The Game was only 74p.

Best 74p I've ever spent. Downloaded OpenXcom as it better than DosBox, More Option etc. Well ♥♥♥♥ Me this game is Sadistic but a hell of a lot fun.

First time I've had to the read the manual for a game in a long time and it's 134 pages long in English only. Not like the modern day manual 10 pages in 10 different laguages.

This game is worth every penny 10/10

The original X-Com is one of the best strategy games ever made. The constant balancing on the edge of ruin, slowly researching the unknown and making headway against a superior enemy, makes for one of the best gaming experiences you could ever have.

If you want something a bit more modern, the new Firaxis Xcom games capture the feel with a modern twist, while Xenonauts is pretty much a slightly improved, HD version of this one.

A classic DOS strategy game centering around base management and turn based combat. Use OpenXcom for mouse wheel support, bug fixes, and general quality of life improvements that don't take away from the original experience. If you can get past an antiquated UI, there is great game here.

This is a strategic game in where you take command of a team and battle different alien races that are attacking Earth. You run you bases on earth while reseaching alien artifacts and improving your armor, weapons, and ships to be able to fight off the aliens and find where they are located to elimintate them.

In my opinion one of the best games of all time, but the learning curve is huge and people which are not willing to spend the time to learn how to play it may get frustrated.
Also, the graphics are simple since game was released on early nineties and have an anime-ish style.

Still one of the best squad based strategy games ever made, though I personally prefer it's semi-broken sequel Terror from the Deep. Take note, Firaxis. This game isn't as pretty or customizable as yours but has a functional strategic aspect, economic aspect, allows the construction of multiple bases, and in fact, has a functional enemy AI that isn't simply a RNG based reactive prescence but something actively trying to kill you on both the geoscape and battlescape from the moment you start playing.

10/10

Would go through the Chryssalid flow chart experience again.

The best tactical game you can buy. This title started the X-COM franchise which has had it's ups, downs, and it's long periods of absence - but it endures. Modded or not, UFO Defense excels at creating a narrative, stories that are told by the gameplay as well as information filled in by the player. You'll develop odd attachments to X-COM agents even though there is little-to-no detail given about them aside from which ridiculous haircut they have. Very difficult, but no in an unkind way like it's successor Terror from the Deep.

I've spent enormous amount of time playing that game.
It has only one minus, the game is old and so is the picture. It takes time to get used to it.
Other than that - it is the best must-play turn-based strategy, in my opinion.

Like in new XCOM, there are two parts - turn-based combat and economical simulator on global map.
In the global part you set up the base (up to 6), build all kind of facilities, in order to research, copy, manufacter and then sell alien technology-based staff, thus making yourself financially self-sufficient. Build lots of storage rooms and collect prescious ellerium. Lots of ellerium. Also, there you hire soldiers, screen off weak, and manualy customize the strong ones. Make up capable squad.

You have a lot of freedom in the global part to make a separate game from it , however the real kicker of the game is the squad combat part.
If you are new to a game aliens will often beat you up on easy difficulty. And it hurts. After 100 h X-COM becomes something like chess. You start using exploits like it was designed to do so. There you can master superhuman difficulty.
After 200h of playing and reading a lot of material from X-COM wiki you can easily kick chrissalid terror mission's butt during the night on superhuman using only conventional weapons. And even then, when you feel super confident, sometimes, soldiers, you became so attached to, you trained so well, all die, due to grenade relay malfunctioning. In one big kaboom. Well... when humankind is on stake, no person is irreplaceable and the fight continues.

Feeling nostalgic i decided to reinstall this again, setup a game in Superhuman difficulty, blast a probe and kill the very first sectoid easy, feels good, in retaliation the Ayylmaos attack my base, i make a stand and kill a bunch of sectoids, one surprises me from behind and wrecks my team with a blaster launcher, 3/4 of my team is dead besides 2, which both later dies by the hands of the last sectoid.

This is why i like this game very much.

What can I say that has not been said already, nothing but personal experience. I was told about this game from a coworker 20ish years ago and started playing but because the game is so old I have not been able to play in years. With the "X-COM: Compleate Pack" on sale I had to get it. This is now the 3rd or 4th time I have purchaced this game because it's that much fun. Some people complain it's hard to figure out but it's easy to find tutorials which I'm sure I will have to do for the games in the pack I have never played. I know this is not much of a review but hey, there are over a 1000 other reviews to read.

Warning this game is Hard. This game is infuriating. This game can be rage-inducing
But man if this game isn't fun...

This game is just another one of those games that comes right out of my childhood. I remember when the first laptops where open to sell to the public and the military had given a free laptop with training on their use (wow right?). My dad got a Compaq Presario, which I still have, This game was on there along with Colonization, Civilization 1-3, and Warcraft.

However this game holds a special place in my heart, I was terrified of this game as a child and would have thought of it as a horror game. But I digress, this game is what the latest game XCOM: Enemy Unknown is based on. This game is insanely hard even though the difficulty setting is a myth. Now mind you this game is old so graphics are not 2016 quality but, that being said this game still charming in a soul crushing way. You can set up every mission with 14 soldiers and you should expect a 50% mortality rate being a good mission resolution. Now on the plus side you can have multiple bases all over the world and set them up how you want. Research is slow and the aliens have a clear and painfuly humbling advantage to you even when you develop laser weapons which are one of the first research option. Which is a testament to its difficulty. Terror mission are the last thing you want to see on your map, and the best solution for the alien menace is to chase them down over the ocean and then shoot them down so as to hopefuly delay the inevitable beating you will recieve by the aliens long enough to get tech that it won't be a massacare. The only forgiving feature is that you don't loose council members and just a small portion of funding which can be suplimented by selling things you make.
Inspite of its age with clunky controls and sometimes absurd difficulty I recomment this game. It is affordable and its sequal, X-COM: Terror From the Deep is even crazier than this game. If you are a glutton for punishment and want a challenge and enjoyed the updated version. I would highly recommend that you get this game

[Edit] - OpenXcom is not a game, it's only a mod. Keep in mind, that I am wrong in the review below!

6.8 megabytes of fun.
It's pretty ruthless for beginners of the series, since you don't have a clue what to do, how to do anything (all the buttons in the fighting mode for example, no descritpion at all) and when to do something. When to buy another base, hangar and so on. This is my first X-COM game I have played in my whole life and it is a lot of fun. But to be honest? I would rather play the new XCOM game called "Enemy Unknown" if you are new to the series, since it features more modern visuals (duh) and is far easier to get into. X-COM: UFO DEFENSE though is not a watered down version is definetly more complex. You get to make more choices, but the downside of all that is its clunkyness. Those game mechanics are more than 20 years old, keep that in mind. I had no problems playing this game on Windows 10, so this is definetly not a worry you should have. My advice anyway: get OpenXcom. You get to play at higher resolutions and you are able to zoom out, which is pretty neat. The game was not meant to be played in 1080p on 27", so OpenXcom is a neat "alternative"...which is free of charge.
So, before you buy - try OpenXcom first. It's more or less the same game, so you get to know if it's worth the 5 bucks for the original.
