Space Invaders Extreme for the PSP is still an incredibly simple game. It's not as extreme and complex as the modern breed of shooter (Ikaruga, Geometry Wars, etc.), nor does it rely on heavily stylized visuals and rhythms to keep it interesting. It's incredibly old-school, but still a refreshing new take on the tiredly approaching rows of identical invaders.

It's like Space Invaders. But EXTREME.
Now, a decade later and with Space Invaders hitting its 40th anniversary, Space Invaders Extreme has been revived on PC. It’s roughly based on the Xbox 360 version but with a some major tweaks and quality-of-life enhancements.
i think its about time that 3rd Party companies take advantage of the PSN store, cause lets be serious here, this game should of been a PSN download for the PSP.
