Sengoku Musou 2 With Moushouden Cheats (PS2)

The quest for Kojiro's fourth weapon is in his fourth stage in Story mode. In order to
unlock his weapon, you must clear 300+ kills as well as kill all Vagabonds (including any
that spawn), help the Ieyasu retreat, kill Hideyori, and reach the southeastern gate
within ten minutes. To do this, you will need a fast horse and a decently leveled Kojiro.
At the start of the battle, clear all the Vagabonds around Ieyasu. Then, run back and
clear the escape point. Wait for two more Vagabonds to appear. Kill one, which will cause
at least six more to appear. Kill them, and wait for Hideyori to spawn in the southeastern
maze-like area. Find and kill him, then quickly go to the southeastern gate. Musashi will
appear in a short intermission sequence. A notice will then appear, showing you the
location of your new weapon. Make sure to get your new weapon before killing Musashi.
