"The Space Invaders concept is nothing new; after all, it originated in arcades 30 years ago back in 1979. You move left and right, and shoot. That's it. Besides Pong and Kenji Eno's One-Dot Enemies, there are few games that could claim a simpler premise. But then in the summer of 2008, Taito quietly unleashed Space Invaders Extreme on PSP and DS, an updated spin on the concept involving bumping techno music, spectacular background visuals (a la Lumines II), and actual depth to the game mechanics. Now the experience is being brought over from handhelds to Xbox Live Arcade, with a number of new enhancements designed to stimulate legions of new Earth defenders."
