DEFCON is a stunning, online, multiplayer strategy simulation based around the theme of global thermonuclear war. The game, inspired by the 1983 cult-classic WarGames, superbly evokes the tension, paranoia and suspicion surrounding the Cold War era.

The player assumes the role of a General hidden deep within an underground bunker, the mission being to successfully exterminate the enemy's civilian population while at the same time disabling the enemy's ability to retaliate. Desperate attempts must be made to form fast, tactical alliances - alliances that may at any moment break-down to become treacherous and very deadly betrayals.

Compete against the computer or even better, compete against fellow Mac or Windows players online for total world domination.

Start by launching battleships, subs and bombers in order to decimate your opponents defenses. Scramble together your alliances, but remember only one can stand victorious.

Do you have what it takes to outsmart your opponent? Can you handle the pressure of global thermonuclear war? Remember - nobody wins. But maybe - just maybe - you can lose the least.

This is an unregistered copy of the game.

I checked website introversion software. DEFCON for sale at $15.00 or stream at $1.99 but stream is intel x64 and introversion at buy at stream and google play and apple application store is intel. Stream system requirement is MacOS 10.11 or greater to run stream. Stream for mac os x 10.7, 10.8, 10.9, 10.10 was drop. This last universal for PPC and intel.

I Checked the game to see if we could register the game but there is no place put the serial in game.
Then I said we need full game upload or help to register this game. Ambrosia did not give register application to register this game.

The serial given is banned by a license server. Turning off Internet connection leaves the status of the code as Unknown. Not sure if that means it is not in Demo mode. I have removed the Serial for now just in case. Please do not put up a working serial number until staff determine that it is OK to do so. This game is still sold by the developer (System specs unknown) and by Steam (Intel only, Leopard compatible). The game also makes reference to it presence on Steam.
