Phantasy Star has been Sega's signature RPG series and a favorite of fans for 19 years.

Of those games, 2000's Phantasy Star Online saw particularly enormous popularity as the first network RPG for home consoles, and received the top prize from the 5th annual Japan Entertainment Software Awards. Over the past five years, PSO has been brought to various consoles and today is still enjoyed by countless users.

Now, combining the story elements of Phantasy Star and five years of network-RPG experience with Phantasy Star Online, the fully-loaded, all-new Action RPG Phantasy Star Universe is born!

Phantasy Star Universe contains both a "Story Mode" for the single player and an online "Network Mode" for multiple players.  Online battles take place in real-time as players collaboratively fight together. In the players' room, each player can create items, and create and customize their own Partner Machinery which is a robot that holds items retrieved in the field, and more.

Phantasy Star Universe: Ambition of the Illuminus is the expansion pack for the popular Phantasy Star Universe game, bringing a more personalized and interactive universe to the acclaimed series. In addition to new enemies, weapons, levels and cities there will be more options available for gamers to further individualize and customize the look of their avatars. Ambition of the Illuminus continues the exciting PSU story online as the player’s personal online avatar is now the central character, investigating and working to restore peace in the chaotic Gurhal System. The player investigates through a series of single-player missions, meeting familiar characters like Ethan Waber from Episode 1, along with other new ones, including a GUARDIAN instructor, Laia Martinez. In addition, the online multiplayer world, with its fast-paced, engaging battle experience for up to six players, has been greatly expanded with new missions, new cities and new enemies.
