Sony has launched its first microtransaction based MMO in Home, Sodium One, developed by Nottingham-based studio Outso.
Sodium One offers smaller games within a larger framework, with the first five levels of mini-game Salt Shooter available for free, and additional content unlockable after purchasing virtual items, priced between 99 cents and USD 4.99.
"The launch of PlayStation Home in 2008 pioneered new ground in interactive entertainment and, since then, increasing support and enthusiasm from our PS3 user and game publisher communities have helped to make this a tremendous first year for the platform," said Peter Dille, senior vice president of marketing and PlayStation Network, SCEA.
"Today we further push the envelope with the launch of PlayStation Home's Sodium, an evolving space that leverages the incredible computing power of PS3 to deliver truly unique, and visually stunning social gaming experiences that you won't find on any other platform."
Sodium One also offers socialising areas, such as a bar, where players can interact and chat freely.
According to Sony, over 10 million PlayStation 3 users have visited Home averaging 60 minutes per visit. Launched a year ago, over 250 community events have been held in Home
