...sorry for the double post
i would suggest tweeking the grab and drag to a set cost per tile pulled...
cut the teleporting bit and make us literally drag them out kicking and screaming every single tileYou hear a violent struggle and screams for help 1 west 2 north!
in/out of buildings, across stretches of open space, and so on
i would probably be dragging nearly dead meatsacks around the city though...so i'm not sure that's a very good idea in of itself
for me it would be fun cause they could wake up any second and blast me for my tom foolery then die from the infection anyways.
..or just use the screaming to flush out active prey...yep...i'd have a ball
