A rather nice show Vik is watching: survivors get ripped apart by ordinary reds.
The guy, with the revolver heroically tried to save his comrade, only to get pinned down to the ground by 3 reds. Ravaged.
That's what happens, when you stop moving.
Zeds will eventually gather so many numbers, that they will cover all exits and swarm you.
After the zeds have left, Vik transcends back into the empty city, occasionally killing the zeds, that get in his way.
Nastya's is not far from here. Just a 5 hour walk.
