DEFCON is a unique RTS from British Introversion Software, known for such experimental projects. The user interface is minimalistic and simple: it resembles a tactical card stylized as Cold War films such as Dr. Strangelove and WarGames.

The game is divided into Defcon phases in which players need to place military forces on a real world map. There are aircraft carriers, submarines, air defense and other equipment capable of either launching a nuclear warhead or reflecting it. The winner in the match is the one who most effectively bombarded the enemy territory. Defcon is a game about pure gameplay, there is no history, as there is no story campaign.

In addition to playing with AI, a player can compete with real people online in multiplayer matches. In total, such matches can accommodate up to 6 people and this significantly complicates the gameplay. Opponents should guess the location of the rival's troops and inflict the most accurate nuclear strike.

Very good Game. Tactically very sophisticated, but hammer Atmosphere and super Community. Will work me in a bit for the next Few days;)

Just the first strategy game a player should play. What for? To make us all think about what is really the fight towards the other.

Whoever saw the Film back then-who will love this Game. Good Implementation! Buy In the Sale, and play in between! Recommended: A multiplayer round among Friends! Let's NUKE.

A very cool strategy game for People who enjoy sitting in front of a Game for several Hours (where everything moves in Slow Motion) and doing nothing. It's a good Game for in between, and especially if it's in the Sale (I bought it for €1-S-And VERY entertaining for that) you can treat yourself to the Game. Even if you don't then (like me, for Example) start It for a long Time, it is still Fun for in between to kill Millions of Civilians with Nukes.

First of all, I want to clarify that I only did the tutorial and that it was enough for me (more than an hour as tutorial so it's slow. Even putting the game on fast forward (X4), some phases like, for example, "advancing a fleet" takes a monstrous time) game to the concept not bad (I think it's really digging) but that seems to be alpha. In the sense that it is graphically simplistic and even bland, tasteless or searching (some games have simplistic but original graphics, here nothing.), that writing is in painful lowercase characters to read, that the system is slow, far too slow and then it's not hot or cold to play while the concept of the game could do a lot more. I mean by that we send a bomb, we see its layout on the map, it annihilated a city of several million inhabitants and there is just a message that appears with the name of the city and the number of deaths. That's all. And the goal of the game is to do this with all the bases and enemy cities (for hours so) and to have at home as little as possible of affected. But it's lame, so impersonal and even boring because it's the ones in front or ours, it doesn't change anything. Simple advice to developers, put images (or even better: cinematics) different illustrating the disasters. Images of Atomic mushrooms, broken monuments, death, desolation, massacre of fleets/planes/bases/soldiers etc. History to Captivate players first. To shock the most sensitive, to please the most psychopathic, and then to make that time passes and that we are curious to see the rest. Your game has potential but you don't use it, it's a pity. So here, in the current state (may 2017), I advise against it, it is boring.
