Voldemort, why do you think that shooting from behind something limits your range? The highest range of any projectile (give or take for wind) is attained when it is shot at 45 degrees above the horizontal. At that angle, you'll clear a horse from anywhere above half a meter behind it. It's when you shoot horizontally, as you seem to want to do, that the arrow goes almost no distance.
Also, the game does contain instant death nodes. Several people are apparently able to create them, including Erika.
And who is going to be creating this virus? Which race is advanced enough to reprogram not just their reality but the operating system their reality exists in?
Oh yes, none of them.
