Syphon Filter: Logan's Shadow Multiplayer hands-on at IGN.

"Our 2006 PSP Game of the Year proved that deep and refined gameplay as well as engaging multiplayer could be handled on the PSP when placed in the hands of a skilled development team. Syphon Filter: Dark Mirror brought one of Sony's characters out of the shadows and onto their handheld without losing a step of espionage intrigue or fast paced action. Later this year, Gabe Logan will return in the sequel to Dark Mirror, Syphon Filter: Logan's Shadow. We've covered elements of the single player gameplay, but we recently had an opportunity to jump into a few multiplayer matches, which will be much more expansive this time around."
