SWAT 4 really had a fairly "punishing" score system based on what actual good police work (in the situation, not like, societally) would be. You'd lose points for shooting people even if they shot first and to get a perfect score you basically had to arrest everybody, implying the very act of shooting somebody means you fucked up somewhere along the line.

I mean sure it's still a shoot the street level gangster simualtions if you want it to be, including gangster hunt gamemodes and such, but you literally couldn't progress to further levels if you went in guns blazing.
