The 360 and PS3 look about the same, slightly different lighting but nothing worth buying one system over the other. The PC does look considerably less polished.

I remember my orange cast coming as an inspiration of michelangelo when I was 3 when i broke my arm.

If it was much cheaper it might be worth it for me.

The PS3 version looks only a little lighter, not quite as dark as the 360, but other than that I notice no differences.

Zombies are best when they can't run fast, it makes them scarier.

Brothers in Arms all the way baby.
