SWAT: Target Liberty's gameplay takes place from a top-down view not unlike Killzone: Liberation. This plays in the game's favor; not only does it give SWAT an original look, but allows you to appreciate the neat environmental details. The top-down view makes it easier to see the smaller details that would likely be overlooked from the traditional 3rd-person perspective. Maps are lit well and packed with small details, such as trees swaying in the breeze or rats scurrying around dark corners.
Sound doesn't make any major strides, though it is more than passable. Officers have just enough force behind their words to command authority without slipping into the overly-authoritarian voice usually used by the stereotypical "tough as nails" drill sergeant seen in movies. On the other hand, enemy voicework can be pretty rough, mostly due to the overly done accents. Gunfire and other weapons noises carry some weight and impact, though the PSP's speakers do diminish the effect.
