Billed by its producer Akihiro Suzuki as an open-world "rebirth" of the series, Dynasty Warriors 9 is coming to PC next month. Now, publisher Koei Tecmo has dropped a new gameplay trailer, five new character trailers and a load of new information on its horses and scrolls. 

From back to front, scrolls are used to craft weapons and items, and are comprised of several collectible parts. Obtained by completing missions or from fallen enemies, new weapons, items and higher ranked weaponry can be crafted by ascertaining each scroll's listed materials.
