Introversion, the award-winning, maverick developer of the hit PC game, Darwinia, will be releasing its eagerly-awaited third title, DEFCON, in September 2006 via Steam and at retail outlets around the globe for $14.95. Uplink is now available as a stand-alone title via Steam for just $9.95 and is also included with Darwinia, the 2006 Independent Developer Festival winner, for a package price of $19.95.

"Steam has made Introversion a commercial success, and brought critical acclaim to Darwinia", said Thomas Arundel, commercial director of Introversion Software. "DEFCON is proof once again that the creation of exciting, unique games does not rely on years and years of development, nor a 100 strong dev team. With the release of DEFCON, Introversion continues to demonstrate that indie developers are at the forefront of exciting, innovative gaming experiences."

"As evidenced by the success of Darwinia, Steam is an excellent outlet for independent developers, such as Introversion, who are breaking new ground with the industry's pioneering titles," said Gabe Newell, co-founder and president of Valve. "With over 10 million registered users, the library of games offered via Steam continues to expand with games from all genres."

DEFCON is an online, competitive, multiplayer strategy game based around the theme of global thermonuclear war. The player assumes the role of a General hidden deep within an underground bunker, his mission being to successfully exterminate the enemy's civilian population whilst simultaneously disabling the enemy's ability to retaliate.
