I'm playing a 3rd-person videogame in which I'm hitting and shooting zombies. It reminds me of the game Dead Rising, but it's not it - the zombies are stronger, and I'm actually a bit tense playing it, as they can easily kill me if they grab me. I am aware that I can avoid most of them, but it seems I'm doing some sort of challenge where I have to kill 1.300 zombies or so. I had about 500 killed, but the tough part hadn't started yet.
