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.

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...

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.

Despite my playtime on official steamrecord I have played hundreds of hours of this game already with the openxcom mod which greatly improves the game via bug fixes, mod implentation and many neat features making it more pleasurable to play. You also get to slaughter as many greys as you want, what else do you want?

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!

Vincent Price's most helpful reviews: X-COM UFO DEFENSE



X-COM UFO DEFENSE is the greatest game of all time that has a title comprised entirely of capital letters. It's also fairly high up there in terms of gaming overall.



If you want to be on the upper eschelon of living by competing against a large scale alien invasion and saving the your planet, and perhaps the galaxy, then this game is for you. Not the terrible remake.



10/10, recommended to people who don't get caught up on lack of certain modernisms.

best hack for this game has to be transferred firestorms equiped with plasma cannons

when you produce a firestorm equip with plasma cannons then transfer to different base
on the first mission the fuel will register zero
do not let it return to base
after every engagement set it to a way point and it will not cost you any fuel

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. Dozens of civilians lost, 5 agents lay dead, and one turned in to an alien. This 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, the 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

This game is freaking awesome, after 20 years it's still amazing.
There are so many good things to say that is difficult to decide where to start ...

- turn based strategic combat, take your time to decide your strategy
- research based on alien captured technology, this keeps me motivated to keep playing
- management of resources of your bases, full control of your assets
- recruit soldiers and see them evolving ... and dying :)
- if you are spending too much money, you could sell things and even fire people!
- air combat is simple and effective
- and every element is this game has an effect on other parts:
A) resources captured in the battlefield will give you new research paths and money
B) research will give you new stuff to build
C) stuff you build will make you more powerful in the battlefield
D) more battlefield missions will give you new resources

As a Sci-fi aficionado this game will give you plenty of funny hours.
Absolutely recommended, if you haven't played, do it now!!
This game is a masterpiece!!

The greatest turn-based strategy game ever made, bar none, with fantastically designed edge of your seat battles, combined with an elegant (for 1993) UI, make this an unforgettable, absolutely-must-own experience.

I ordered one rookie to walk out of the landing craft after waiting for a UFO to show up for half an hour.

An alien shot him and the rest of the squad panicked and shot each other.

11/10 would play 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.

Pros
-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

Cons
-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.

This game is for the few who want extreme realism and control over everything. You have to buy every single cartridge of ammo or every single rocket yourself, then equip them to your troopers. You pretty much have to do everything yourself. Never forget to research new technologies, then construct the results. There is no tutorial, once you position and name your first base, you are entirely on your own. If you have never played it before I'd reccomend either Xenonauts, which is VERY similar but slightly mordenized or the new XCOM game, which is more simple and user-friendly.
