My mind seems to be a bit scrambled at the moment, so you’ll have to forgive me. I just finished eight consecutive games of Score Rush on Xbox LIVE. Imagine being a white blood cell, drifting through the bloodstream on your way to, I don’t know, say a white blood cell rave party, when suddenly a virus appears.
As a fan of science, with no technical expertise or experience, I still imagine playing Score Rush is very similar to what would occur: the white blood cell would immediately fire millions upon millions of bullets at the intruders until they died, and gave up their experience points.
