where exactly was it seen that they can hold weapons now...?
im just curious.
and yeah, looks like they were beginning to learn faster and faster.
in Nacht Der Untoten they were hardly a threat, seeing as they hardly reached through the door (until BO where they patched it an they smack now)
then Verruckt is where they began to swing by the door, and Shi No Numa had the fastest zombies (im guessing they discovered how to run faster?)
and then (as mentioned) in Der Riese they began to climb the fences.
Kino...eh... i didnt see much change other than the fact that they now began to come from ceiling locations too and above buildings....
they bob to the side if aimed at (displaying that they discovered if aimed at, they will get shot)
they did the spetnatz roll (probably the same reason as when the move to the side)
and lets not forget that huge jump in the main room if youre on the second floor of the spawn area and theyre down below...
yeah, these look like theyre going to be scary smart =/ :o
