But it is. It's my body, and my soul. Somehow we've had greatly varying experiences though because unless the zombie is charging me, I can take my time and put down 6 zombies with 6 bullets in contagion. I can sometimes do that in NMRIH too, but more often I just hear "SPLAT", see a bloody spot on their face and they keep coming forward.
Either way, both have their pros and cons, like Contagion not having a chainsaw.
