Summary: The gameplay and animations may be pretty smooth for a fps on the Nintendo DS but the controls ruin it for me. Just because the stylus is there doesn't mean a game should use it - and this is one game that does not benefit from using the stylus as a control input. It's awkward to hold and use the buttons AND stylus all at the same time - I can't do it without setting my DS on my leg or another surface.
Summary: I wasted $20 on this game, and it is the worst game EVER! I absolutly HATE this game. There is NO replay value, no good story, and terrible graphics. I give this game -500/5. I know you may want this game with all your heart, I did to. But it is not worth it.
Summary: First of all the idea of aiming the weapon is hideous - having to aim perfectly with the pen, firing while pressing down the left/right buttons, using the control movements requires more than the pair of hands you already have. I almost dropped my DS a couple of times while playing this game. The game itself is good but on this platform it is frustration. Buy the game on a different system.
Pros: Unfortunately there is none that I can tell
Cons: COD4 is meant to be played on a more sophisticated OS
