I don't get what's so special.
Unless Iban was a zombie AI, I didn't see anything different.
At the beginning of the movie, that is Iban. You can also see a shadow of him respawning at the end.
Will this overwrite any other zombie mods if i download?
I'm not sure. It might interfere with Rot's though.
The difference between zombies that jump and crouch and those of this mod is that these do not do so needlessly; these zombies do so to avoid and navagate obstacles that are in their way and find out how to manage them in the right way.
Also, as far as I know,
there is no specific release date on this yet. The mod release and public server launch will be on October 31, 2009.
