Description: Seven games from SNKs gorgeous, delightfully playable 2D side-scrolling shooter series may sound like a recipe for broken PSP buttons as a result of the relentless use theyll endure.

Because despite the odd irritating flaw as a result of the conversion process, there is little on Sonys handheld that can match this for a quick, gratifying dose of shoot-em-up goodness.
