Syphon Filter Combat Ops

Syphon Filter: Combat Ops expands the multiplayer experience presented in Syphon Filter: Dark Mirror and Syphon Filter: Logan’s Shadow, by adding mission and combat modifiers, map editing features, and the ability to share user-generated content. For the first time, users have the ability to create their own multiplayer missions with the ability to edit objectives, avatars, spawn points, and zip line locations, then upload them to the game server to share with other PSP owners worldwide. A ranking system for shared maps allows players to rate maps they have downloaded and played.
