Call of Duty 4 (yes, there is a DS version)

I saw it at work and was wondering if anyone had actually played the DS version.

Obviously, it's not going to be the graphics powerhouse it is on the 360 or PS3, but is it fun at all?

Looks hiliarious, but amazing how this shows up on DS, yet not PSP..

Yeah, I've played it. It's okay, but nowhere near the standard Metroid Prime Hunters set for FPS gameplay. The framerate's all over the place... spending most of its time around 40-45 fps, piking well into 80-90 fps it seems, then stuttering at random points. That was a bad explanation, but if you try it, you'll see what I mean. The controls are sloppy, and aiming feels "heavy" (if that makes sense... it's hard to look around). It wasn't bad, though.
