Starting on June 30th, Ambition of the Illuminus will be a free download on the Xbox Live service! Previously, this Phantasy Star Universe expansion cost 800 points ($10 USD). This download is 2 GB in size and requires Phantasy Star Universe to utilize it. Considering that Ambition of the Illuminus has been made a requirement for PSU's online play, this move will be welcomed by new players. You can discuss this update in this on-going forum thread.
