For those of you that haven't kept up, it is absolutely amazing that there are still things that the zombies community can't figure out a month after the games release.
Treyarch did an amazing job. For example, at games launch you could trick the pack a punch in to upgrading the Apothican Servant WW, which was a glitch that got patched. To this day, people have been digging in to the games files to try and figure out how to upgrade it, and still even with all the code sitting in front of them haven't been able to figure it out.
There is also supposedly a second version of the Apothican Servant, that at this point, we have a 3 second clip of, and the code to back up the theory. Still can't figure it out. Also a possible third version of the sword that hasn't been figured out.
The three year cycle has given 3arc so much time to well fuck with the zombies community, and I can't imagine we have even scratched the surface yet of what they have in store.
If Shadows is any indication, the zombies community is going to be in for a huge hunt going forward. We will still be finding things in 3 years.
