6 - Braingathering
We fought our way to the main server room. The zombies realized that they run
out of humans sooner or later, so they started to build machines to create
humans for them to eat. Those machines have a special code which is only known
to the zombies. This code is capable of destroying all breeding-machines. Now,
it's all up to you to get this code and tell us so that we can destroy all
machines.
