Microsoft sprung a surprise at Tokyo Game Show when they announced Space Invaders Extreme would get an Xbox Live Arcade port. Great, but what if you already have a copy of Space Invaders Extreme? According to the ESRB, Space Invaders Extreme for the Xbox 360 is Space Invaders Extreme plus Space Invaders.

“This is an arcade-style game in which players eliminate rows of alien space ships in order to clear game boards. The game includes the original version of Space Invaders, as well as new stages, bosses, and alien types.”

Classic Space Invaders would be a sweet addition if there are separate online leaderboards for it. The thought of “new stages” is tantalizing, but this is likely a reference to the content already created for the DS/PSP release of Space Invaders Extreme that makes it different from classic Space Invaders.
