Actually as far as I can tell from looking at the instruction manuals for both there are actually two exclusive modes on the PS3. They are:
Assassination: One team must find and eliminate a high-value asset while the other team tries to escort him to the extraction zone.
Total Conquest: Team based capture-and-hold game mode where each map contains 3 Mobile Radar Installations. To win, a team must capture and maintain control of each Mobile Radar Installation to accumulate a predetermined number of control points.
And to asxtb I did indeed misread your post. I haven't played off-line multi-player yet.
