Now why on earth would Dynasty Warriors need a town? Everything outside of combat is done on the menu screen, after all.
In Strikeforce, Koei added a City, a place where your character can chill, interact with NPCs, and store loot. Certain NPCs can teach you new talents, making you even more overpowered in the field; you can also upgrade or create weapons at a blacksmith NPC, or take a chance at the fortune teller NPC. As your hero's reputation grows, other warriors may come crawling in and hanging around your City. They'll level the city while you're out killing peons.
Now "The City" walkthrough is just the first episode in Koei's video walkthrough series for Strikeforce. More will be released throughout the week, going over some of the changes seen in this game, including online multiplayer and crazy bosses.
