Ambrosia Software has released its game of nuclear Armageddon, Defcon for the Mac.

The company developed the Mac port in partnership with the title's original London-based developer, Introversion Software, Defcon is an online, competitive, multiplayer strategy game based around the theme of nuclear destruction.

The Mac version is completely interoperable with the Windows version for network play. The game support multiple human players and also boasts built-in AI opponents.

"There exists an ever growing group of gamers who are converting to Mac and we want to make sure they enjoy playing all of our games," said Mark Morris, Introversion Software's managing director. "It's been great working with Ambrosia and I can't wait to see the reaction once everyone has started playing."

"Global thermonuclear war has never been this much fun," said Andrew Welch, Ambrosia Software's el presidente. "It's macabre, but plotting for your friend's total annihilation is perfectly satisfying."

Defcon is inspired by 1983 cult-classic film, WarGames. It attempts to evoke the tension, paranoia and suspicion of the Cold War. Released for Windows last year, the title won critical acclaim across the PC press.

The game of thermonuclear destruction will set you back $25.
