[Update:Koei Tecmo has clarified a few of the details about the demo version of Dynasty Warriors 9. It will be heading to PC on November 1 and PS4/Xbox One on November 7. Players will be able to select three of the officers from the cast of 90, so Lu Bu is on the table.
Along with that, a second season pass is coming to the game. That will be hitting PS4 on October 30 while Xbox One and PC will get it on November 1. This season pass is set to include, "a variety of additional weapons, costumes, scenarios, and a plethora of useful materials, including various types of coins, a book of Musou, and exploding arrows."]
Koei Tecmo has announced that Dynasty Warriors 9's co-op and split-screen patch will be going live tomorrow. As the name suggests, it will bring cooperative multiplayer to the latest installment of the Warriors series.
There is a restriction on the distance each player can be from each other (since this is an open-world game), but both of you will be free to do as you please. As for how the online will work, you can play with your friends or total strangers online. Cross-platform won't be a thing, so don't get your hopes up for Xbox One/PS4 shenanigans.
If you're unsure if Dynasty Warriors 9 is for you, a demo will also be launching on November 1. It will feature co-op play and give you a taste of the main campaign by having three officers available. We don't know which ones are available, but there are rumblings of allowing users to purchase individual officers for around 200 to 400 yen depending on the length of each scenario. Trophies and achievements won't be unlockable from the demo version, which mostly makes me confused why you can purchase characters.
