Giana Sisters: Twisted Dreams is due out on PlayStation Network "later this month," Black Forest Games announced on the PlayStation Blog. This is a delay from an initial launch window of March; Giana Sisters: Twisted Dreams landed on XBLA on March 20, and the PSN version was slated to hit "a few days later."
Not to worry, though – we found Giana Sisters: Twisted Dreams on PC to be beautiful and challenging, and absolutely worth a history embroiled in scandal and bankruptcy. It should be worth a few extra months to play it on PSN.
