Yes, the videos you're seeing are running on a PSP. Not a PS2. Not a Wii. But a PSP. The dense foliage, the beautiful rays of light shimmering down to the ground, the individual blades of grass ... this is all real, and all on the handheld. Look at the fog in the background: this isn't the muddy in-your-face fog from the N64 era. Look how you can see through it, just as you would real fog. This is one beautiful game. But don't just stare at the graphics. Look at the enemy and partner AI. Watch for the commands system, and the intelligent way you move around the environment.
