It's not THAT bad.
Sure the graphics suck, but I doubt if I could do better. The sound is okay, but it was wierd that a clip hitting the ground makes a big *THUMP* sound. It was a bit goofy when the characters moved around, too. The biggest let down was that there weren't any innocent bystanders getting shot, or structural damage.
Eh, I say it's a three at best, two at worst.
