PS3 Home Xi expands again

Alpha Zone 2 now open.

Xi, Sony's alternate reality mystery game set in PlayStation Home, has just got bigger.

The second Alpha Zone is now open. Inside are numbered screens on walls, detailing more games and puzzles. On the floor is a mysterious yin-yang symbol. Could it reflect the light and dark, good and evil theme of the area?

Earlier in the month we brought you the news that the secretive PS3 Home manhole cover was open, revealing for the first time the virtual world's Maintenance area.

And, before that, we told of Xi spreading out from the virtual world into the real, detailing a clue that lead players to one of the giant Xi jigsaw puzzle billboards dotted across the world.

To help unravel the mystery of Xi, jump into PS3 Home and head for the Xi logo graffitied on the wall in Home Square. But before you do that, be sure to check out these exclusive screenshots of Alpha Zone 2.
