About This Game

Inspired by the 1983 cult classic film, Wargames, DEFCON superbly evokes the tension, paranoia and suspicion of the Cold War era, playing on the fascinating aspects of psychological gameplay that occur during strategic nuclear warfare.
You play a General hidden deep within an underground bunker. Your mission is to successfully exterminate your enemy's civilian population whilst saving your own. Points are awarded or lost depending on both the efficacy and thoroughness of your nuclear vendetta and the number of your own civilian deaths. In order to win you must wipe out the enemy population and simultaneously disable the enemy's ability to retaliate against you. This is an extremely difficult task since launching an attack on the enemy exposes the positions of your own Ground Silos, Subs and Bombers the moment they launch nuclear weapons, making you extremely vulnerable and exposed to a crushing counter-attack.
Desperate attempts must be made to form fast, tactical alliances, alliances that may at any moment break-down to become the treacherous and most deadly of betrayals. Everyone looks to each other in a state of nervous suspense and paranoid accusation. In all-out nuclear Armageddon, everybody dies, everybody loses, you just have to make sure you lose the least!

The only thing I can put here are some quotes from the game itself and elaborate on them. "Everybody dies," is not an understatment. Doing well at this game is being nuked to hell, and doing poorly is getting nuked to hell, and then some. This game is brutal, addicting, and the AI is one heck of a challange. "It's not about winning, it's about loosing the least." This statment fits the play through so well. When you "win" you don't feel like you won, because you didn't. You feel like you've been tranpled on, but managed to make it out, dealing tons of damage to the person that hit you. You can't win this game, simply lose the least. Never-the-less, it is rewarding to see that you made it... with bilions of deaths world-wide.

Not single player? Pass. By the way, I played through the tutorial and forgot to close the game when I alt-tabbed. So that's why it shows 9 hrs played.

Was not fun. Multiplayer does not work. Tutorial was terrible. No singleplayer.

I'd rather have decided to go play a nice game of chess then paying for this game.

Do not buy this if you don't have patience to live though nuclear annihilation.

Its boring.

This game is a great game, I have played it a few times before and it is quite fun. When playing the game it feels like an old game because of the 1980's style map, but it is a great. The best parts (to me) are being able to fling nukes backwards and forwards trying to beat up as many of the enemy's places as possible. Another thing that is actually quite fun to watch is when two different countries team up (like america and russia teaming up or something) then a few minutes later one of them shoots down the other's plane or blows their boat up. Suddenly you'll see battles happening all over the place and then nukes and it just gets really amusing to watch. This game has many fun achievements to get like the achievement where you nuke santa while he flies overhead and many more! I recommend this game to those who would want to play a strategy game where you just direct things to places and wait for an explosion or something to happen but the game is more than that. I also recommend it for those who want to see what WWIII could've looked like and for those who want to be 'pressing the button that destroys it all' (doomsday button)!!!!!!

Channel Five News: "Breaking news: The US has launched a pre-emptive nuclear strike against North Korean ICBM silos causing collateral damage to several large cities and thus inflicting more than a million casualties. The exact numbers are not certain but the city of Pyongyang was hit directly as five silos where reportedly located in the center of the North Korean capital. The decision of dropping nuclear warheads on North Korea has stirred massive debate between UN members on whether or not the US should be punished for its deeds. China and Russia are calling for a world wide embargo on US goods and ..."

Dear Charlene,
I miss you. How are you? Are the kids fine? How is the weather in New York? I guess you've heard about the Chinese surprise attack against the Pacific Fleet? Yeah. I don't think that I'll be home soon. High Command is deploying my squadron to Anchorage, Alaska. I hope that this doesn't escalate.
Love you,
Mick.

Mick,
The President has just said on TV that we're at war with China! He said that we are mobilizing our nuclear assets! What does it mean!? And why oh why did we have to attack North Korea? What was it good for? Please Mick. You've got to come home.
Charlene

Charlene,
I can't go home. I've got to serve my country. I can't just let them kill Americans and let them get away with it! We had to nuke North Korea or we were going to be the ones being nuked! Anyway. Please take care of the kids...I have to take off in an hour or so...I could not come back alive. Just...take the kids, go to Vicky in the countryside. She may be crazy but she lives near a nuclear bunker. I'd feel better knowing that you and the kids are close to a bunker. ♥♥♥♥ might just hit the fan. I love you Charlie,
Mick

Mick! I've just seen in the news that the Chinese are readying their nukes! I'm taking the kids to the subway! Please be safe and know that I love you too!

- Lt. Michael Davidsson 18:45:17: "Control. We're going dark in exactly five minutes. What are our orders?"
- Control 18:45:47: "Standby 82-1068. We're transmitting your orders. God's speed."
- Lt. Michael Davidsson 18:46:07: "Control. Are these orders legitimate? I me...
- Control 18:46:09: "I can assure you that these are legitimate and correct orders Luitenant. POTUS has called for them as OPFOR has launched its nuclear arsenal."
- Lt. Michael Davidsson 18:46:25: "That can't be true! When did they have the time to launch?!"
- Control 18:46:34: "That was just about two minutes ago Luitenant. Diplomacy has failed. Now do your job and make your country proud."
- Lt. Michael Davidsson 18:46:52: "*Audible sigh* Roger that Control. May God have mercy on our souls."
- Lt. Eugene Rodriguez 18:46:59: "Are we really going to nuke Beijing? This is madness!"
- Lt. Eugene Rodriguez 18:48:02: "Sir are you going to say something or not?! I call that we immediately turn ar..."
- Lt. Michael Davidsson 18:48:07: " Dammit Eugene! We have to do this! This is what we have trained for! Now stick to your orders!"
- Lt. Eugene Rodriguez 18:48:14: "I refuse! I'm taking us back home! I don't want to be remembered for murdering millions of people! They're people Mick!"
- Lt. Michael Davidsson 18:48:21: "I don't care! Orders are orders! Nuclear payloads are going to rain down on our friends and families! We have to avenge them!"
- Lt. Eugene Rodriguez 18:48:29: "NO! Wa...Wait! Mick! Come on! We've been friends for like forev..."*shots fired*
- Lt. Michael Davidsson 18:48:35: "I have to do this Eugene...there is no other option."*loud breathing*
- Control 18:49:30: "Luitenant. You have to go dark in a few seconds. Please confirm that you and your co-pilot have understood your orders."
- Lt. Michael Davidsson 18:49:37:"Control...Eugene refused to comply. I had to shoot him. He wasn't ready. I...I..."
- Control 18:49:48: "It's okay Michael. You did what you had to do. Finish your mission. I think that Baghdad's international airport will be your best landing spot. Anchorage is a viable target for nuclear retaliation now. Russia is readying its own nuclear arsenal for launch. I'm proud of you. America is proud of you."
- Lt. Michael Davidsson 18:50:04: "Thanks Jim. I hope you make it. I'm going dark in three, two, one"
TRANSMISSION ENDED.

AFTER ACTION REPORT: 17-04-2015 19:00:00 "OPERATION TOOTHPICK"

Unit With Highest Efficiency:
- 82-1068 Spirit of New-York - Target: Beijing - Pilots: Lt. M. Davidsson and Lt. E. Rodriguez - Status Unknown - Awarded Medal of Honor by POTUS
Conclusion: OPERATION TOOTHPICK IS A SUCCES. CHINESE NUCLEAR ARSENAL IS DEPLETED. CHINESE POPULATION IS HIT HARD. US HAS SUSTAINED LESS MEGADEATHS THAN CHINA.
Current Status of National Affairs: THE CHINESE FIRST STRIKE HAS DESTROYED OVER 50% OF OUR NUCLEAR CAPABILITY AND 65% OF OUR CITIES. WE BELIEVE THAT WE ONLY LOST 20% OF POPULATION.
Current Status of International Affairs: CHINESE THREAT DESTROYED. RUSSIA IS READY TO FIRE ICBMS. ENGLAND IS READY TO FIRE ICBMS. FRANCE IS READY TO FIRE ICBMS. PAKISTAN IS READY TO FIRE ICBMS. INDIA IS READY TO FIRE ICBMS. SOUTH-AFRICA IS READY TO FIRE ICBMS. BRAZIL IS READY TO FIRE ICBMS. OUR REMAINING NUCLEAR ARSENAL IS READY FOR LAUNCH. NUCLEAR APOCALYPSE IS IMMINENT.

POTUS signing off.

Have only been playing the game for a very short while and have found myself in a very Fallout style 'Great War' situation between China and the United States.

- I sweat nerviously as minor skirmishes lead to my Naval power being destroyed beyond a pair of Submarines hiding away in the Ice Caps.

-The Chinese Navy has prevented any Recon Aircraft from penetrating to find the Chinese silo and Radar locations.

-Nearly an hour passes in DEFCON One and neither side takes the final steps toward the Nuclear Madness, I sneak my Submarines deep into Chinese waters, one off the coast of Tokyo, the other off the coast of India.

-I step away for a moment to make dinner.

-Alarms blare, Panic ensues. I return at a dead sprint stubbing my toe on a table and falling to the floor screaming in agony. I shout to my Girlfriend

"FOR THE LOVE OF GOD FIRE EVERYTHING!"

-In the Chaos, Silo's spit forth their rods of death at major Chinese Cities. Aircraft Scramble from the assorted airfields located in Alaska, Fighters to draw fire for the Bombers carrying their horrifying cargo. The Chinese respond in kind, their Silos bursting to life. My submarines seize the opporunity to deliver a harsh counter attack firing their arsenel at Chinese silos.

Soon i manage to collect myself and make my way back to my computer horrified at the propects that await me. To my even greater horror i realized something.

The Chinese didn't fire first.

A TV show my son was watching in the background had alarms and threw me into a panic.

Soon after the casualty reports came in.




9/10 would plunge the world into a Nuclear Apocalypse because of a kid's TV show again.
