The combat is nothing special. What makes Alpha Protocol stand out is the social manipulation aspect. The MC has a personal relationship with every named character and you can make them love or hate you depending on your actions, with both having benefits.
It uses the conversation pie thing that Mass Effect does but to better effect. In Mass Effect you're just making boring "paragon" or "renegade" choices but in Alpha Protocol it's not a moral choice, you adjust your personality to be professional, suave or aggressive depending on how you're trying to manipulate the character you're speaking with.
