CydoniaX said:The worlds first console-based Alternate Reality Game starts today in PlayStation Home.
Called Xi , the adventure takes place in a series of secret areas in Home and beyond changing day by day, week by week, in real time. Anyone with a PLAYSTATION 3 can join in the fun for free in English, French, Italian, German or Spanish.
To discover the mystery of Xi, simply log on to PlayStation Home and look for the graffiti on the wall in the main square. Find that, and all will be revealed .
