Sony is adding an MMO to the ranks of games currently offered on PlayStation Home. Sodium One launches today and is a sci-fi themed game involving a variety of games and community events. Players will begin their experience in Sodium One with VICKIE, an NPC who is responsible for assigning quests. The first game is "Salt Shooter" (Are we sensing a theme here?), and sends you off in a tank to fight robots.
Sony has adopted a pricing structure that is becoming increasingly familiar: free-to-play to a point, with the option to break out the credit card and purchase more in an a la carte system. You can play the first five levels free, and additional items are available for purchase to help you advance beyond that.
The game launches today for PlayStation 3 owners who have a PlayStation Home account -- just look for the teleporter in the PlayStation Home Central Plaza and you're on your way.
