It's a little like R6: Seige meets Door Kickers, with hints of Vegas 1/2, and a splash of the original Rainbow Six (PC - 1998). It's also one of the first games that I enjoyed for 100's of hours trying my best throughout the entire campaign not killing the suspects! Sad to say that R6: Seige (and similar games), although decent, just don't seem to fill the same hole as SWAT4, and the gaming industry has had 15 years to provide an equal and still nothing!
