Pursuit Force looks very interesting on the top, but lacks innovation.
The game usually requires you to either reach a certain point on a level without dieing, or to kill a specific enemy. Most of Pursuit Force is vehicle-based, but there are portions of the game that bring in the aspect of a 3rd person shooter as well. This helps break in the same old boring stuff, and keeps your attention. Although it does give you these sequences of on-foot combat, they only last for very short periods of time and will usually take you about 2 minutes to complete on your first try.
Graphics: A step above the standard of the PSP, with very few framerate problems.
Story: Not all that interesting.
Multiplayer: None.
Controls: Quite well laid out, surprising for the PSP.
Sound: Not interesting or important, with music that constantly replays.
