(adsbygoogle = window.adsbygoogle || []).push({}); here is my theory when the clock strikes it may have a possibility when the clock strikes at der riese the zombies will start mutating and it may have to do with the eclipse and a possibility with electricity going down and it will cause the drawbridge from the trailer to go down that means no perks no pack a punch no traps. Its like an insta kill or nuke for the zombies.

Sounds very challenging and fun but i dont know how theyd fit that in

I heard it was the time u had to link the teleporters

yup also what i heard

The clock is to show how much time you have left to link the teleporter after you've linked the first one.

^ yup linkage of teleporters
