New Characters or Zombies?

[evslarg]

yeah... i was wondering when a zoo would come up cuz all the animals would be like " ROAAAAAAR" and the zombies would be like " DERP NOISE RUN TOWARDS IT" but all the animals are in cages.....

[patient zero]

Maybe some kind of hive zombies that coat areas in webbing/membrane akin to something like Alien, would mean they could detect survivors without seeing/smelling them, could make for some tense scenes trying to escape an area without touching/stepping on the zombie slime and alerting the horde?!

ps we already know that animals can't be turned; Marcus had his attack dogs that he said, "couldn't be turned"
