The OnLive cloud gaming service is set to launch in the US on 17th June.
The service allows players to access PC games from 2K, EA, THQ, Ubisoft and Warner Bros. The games run on OnLive's beefy servers and players control them remotely through the OnLive client.
OnLive will initially charge a subscription fee of $14.95 per month and special offers and longer subs deals are also planned.
Once subscribed players will need to pay extra to buy or rent games. However, the first 25,000 users who sign up will get three months' subscription for free.
The OnLive service will be offered across 48 US states at launch, and is initially aimed at PC and Mac users.
Community features include voice chat, gamer tags, user profiles and free demos. It will also be possible to pause and resume games while accessing these features.
Confirmed games include Mass Effect 2, Dragon Age: Origins, Assassin's Creed II, Prince of Persia: The Forgotten Sands, Borderlands and Metro 2033.
The company intends to announce details of its MicroConsole TV adapter for TV sets later in 2010.
