The mystery behind Xi has finally been revealed. Today, for the first time, all visitors to PlayStation Home can discover the full truth about Xi, Jess and the alpha zones beneath our virtual world.

All the Xi spaces will stay live for a few weeks yet, so if you want to finish off any of the games and puzzles – or if you’ve never experienced Xi before – you still have a chance to play and explore.

When you’ve had your fill of mini-game goodness, you can go to the Xi Hub and face the story’s dramatic conclusion. Just make sure you’ve got everything you want out of the game, because once you’ve seen the ending, there’s no going back.
