Play Battle of Nagashino. To obtain the Heaven's Sign (Tenson Kourin), you must manage some forts and strategically eliminate your enemies. First, take Nagashino Fort directly in front of you (defeat the general outside to open the doors, then defeat both generals inside to claim it). Then move south and protect the other fort by defeating Tadatsugu Sakai. When Tadakatsu Honda and Hideyoshi Hashiba appear and attempt to pincer your commander's base from north and south, kill them both before they can enter the base. It is safer to get Tadakatsu first and on the way rout Mitsuhide Akechi. After the event where it begins raining, thus nullifying Nobunaga's muskets, Shingen will order a charge and a few moments later the supply team will show up from the south gate and sprint to the east.
