A fairly impressive technological showcase for the PSP at the time of release, demonstrating that such a compact device could handle large levels filled with enemies and vehicles. The game isn't long enough to overstay it's welcome and features more variety in missions than you'd expect from a glance.

The vehicle leaping/hijacking is the real star of the show, especially when combined with the mid-air slow-mo shooting, it really never gets old.
However, some large, unprecedented difficulty spikes harm the experience somewhat.
