lol nice one Biggus. I had a similar experience the other night with a survivor, we were both fresh spawned with no weapons and trying to cycle/loot the same building for some.
We kept doing laps of the building bringing in zombies to the other for about ten minutes, back and forth like tennis.
I ended it by running into town and stirring up about 30 of em, I did reverse loops and then back again until they were practically running circles around it.
He broke for it, they gave chase, I strolled into the building and got back to searching
