OnLive, the cloud gaming service announced a year ago at GDC, will launch on June 17 in the US.
The service, which grants access to a range of PC games from EA, Ubisoft, 2K Games, THQ and Warner Bros, will charge a subscription fee of $14.95 per month, with special offers and longer subscription deals also on the cards.
"This marks a huge milestone for both OnLive and the interactive entertainment landscape as a whole, changing the way that video games are developed, marketed, accessed and played," said Steve Perlman, Founder and CEO of OnLive. "We are opening the door to incredible experiences for gamers and enormous opportunities for developers and publishers."
Users will also be offered the chance to buy games over the service as well as rent, and the first 25,000 users who sign up will get three months access free. The service is to be offered across 48 states at launch
The service is initially aimed at PC and Mac users. Features include voice chat, gamer tags, user profiles and free demos will also be offered, with users able to pause and resume games while accessing the cloud service.
"The OnLive Game Service creates a new opportunity for consumers to play the latest games without spending hundreds of dollars on a hardware system to make it happen," said Mike McGarvey, COO of OnLive. "As a Mac user myself, I'm excited about the opportunity to help bring high-end gaming to this new and significant market."
First titles confirmed include Mass Effect 2, Dragon Age Origins, Assassin's Creed II, Prince of Persia The Forgotten Sands, Borderlands and Metro 2033.
The company has said it will announce details of its MicroConsole TV adaptor for TV sets later in the year.
