Syphon Filter 4

This question is on the video game section but as no-one has answered it, I thought of putting it here.
(1) Is there any way of getting Team Efficiency without a multiplayer connection?
(2) Are there any cheats for this game - if you know any, could you say some or a website that has these cheats

Thanks

This being for PS2 - this game.
