Syphon Filter: Logan's Shadow contains a robust multiplayer experience allowing up to eight players to compete online in four-on-four Ad-Hoc and Infrastructure gameplay. In addition to Deathmatch, Team Deathmatch and Rogue Agent, the game features two all new gameplay modes, Sabotage and Retrieval, providing players with five multiplayer game options. Sabotage is an objective based mode where players have to work together to achieve a goal which will change from map to map, creating a new experience with every round. In Retrieval, players attempt to steal an object from the opposing team and return it to their base.

"Syphon Filter: Logan's Shadow promises to live up to the high expectations following last year's IGN PSP Game of the Year, Syphon Filter: Dark Mirror," said Jeff Reese, director, software product marketing, SCEA. "Syphon Filter: Logan's Shadow is an action-packed espionage thriller, which combined with the newly designed PSP, is a great gift idea for the gamers on your list."

Syphon Filter: Logan's Shadow finds Gabe Logan once again using a combination of stealth and "run-and-gun" gameplay, as he is called into action when a dangerous new technology is hijacked by a criminal extremist group, while facing the possibility that his long time partner, Lian Xing, is a double agent. For the first time in the Syphon Filter series, players engage in full 360 degree underwater combat and take control of new weapons, such as the bolt pistol and spear gun, in a story that takes Logan from the depths of the Indian Ocean to the deserts of the Middle East. Using the Havok Physics' engine, players have the ability to interact with barrels, boxes, and enemies using real world physics. Building upon the control configuration developed for Syphon Filter: Dark Mirror, multiple control layouts permit gamers to choose precision aiming at all times or enable the player to select a more classic style controller for easy play and target lock shooting.

Included with Syphon Filter: Logan's Shadow is a demo of Syphon Filter: Combat Ops. This special preview allows players to edit multiplayer maps and share them with other PSP owners.
