Ambrosia Software along with Introversion Software today launched the Mac version of DEFCON, an online multiplayer strategy game based on the theme of thermonuclear armageddon. The game was inspired by the 1983 cult-classic film WarGames, and is designed to evoke the tension as well as the paranoia surrounding the Cold War era. "Global thermonuclear war has never been this much fun," said Andrew Welch, president of Ambrosia Software. "It's macabre, but plotting for your friend's total annihilation is perfectly satisfying." DEFCON is available online via Ambrosia's website for $25, requiring Mac OS X 10.3.9 or later.
