Expansion to the PC version of the console RPG, featuring additional upgrades. The map screen is enhanced and there are more than 150 new items, players go up to level 20 and there are 10 additional music tracks. When compared to the console original You can now access shortcut commands, visible at the bottom of the screen, a new character, Momoka, appears in the game's lobby area and offers up new quests, and there is a new "Team System," where you hook up with team members and even communicate with one another from across different ships. Sonic Team also worked on improving the graphics and control. The biggest change though is a good means of keeping people from cheating. PSO: BB is an online-only experience on PC. Character data is now stored on the game servers far out of reach from those who would modify their characters to give them an advantage in battle.
