the zombies stop dying from weapons around the 40's. i don't like to use traps until the 40s ,so i guess it takes me longer. but none the less the rounds end up lasting FOREVER getting to round 50 is not even half of getting to round 99, because the rounds get so much longer.If you check the leader boards you'll see pretty much the same name in multiple spots on the same map, with just one letter difference or number . it took 14 hours, to get to round 57 for me and my partner on kino, minimal bathroom breaks with a crawler. i'm not saying it can't be done, but i don't think it is possible for one team to legitimately get there, on the leader board at least. after a while you start getting sleepy, and sloppy.if you swap out partners, i think it would be.
