This is a partial save for Samurai Warriors 2 from me. I packed the files into a .rar file. Unzip to My Documents\KOEI\. You should back up your old files. All of the characters are now unlocked. I will begin working on getting the rare horses and bodyguards when I have time and update the file again if anyone cares.
NOTE: From this point on, all bodyguards are cheated to 99999 exp because I'm too lazy to level them.
Characters Unlocked: Yukimura Sanada Keiji Maeda Nobudana Oda Mitsuhide Akechi Kenshin Uesugi Oichi Okuni (Level 50) Magoichi Saiga Shingen Takeda Masamune Date No Hanzo Hittori Ranmaru Mori Hideyoshi Toyotomi Tadakatsu Honda Ina (Level 50) Ieyasu Tokugawa Mitsunari Ishida Nagamasa Azai Sakon Shima Yoshihiro Shimazu Ginchiyo Tachibana Kanetsugu Naoe Nene Kotaro Fuma Musashi Miyamoto
4th Weapons: Ina (Coiled Viper) Mitsuhide Akechi (Gilded Talon) Nobunaga Oda (Demon Regalia) Okuni (Raging Sun) Ranmaru Mori (Iron Vengeance)
Okuni is obtained by winning once in the Sugoroku Mode. that's the stupid side minigame with the dices. i had a much easier time using Nobunaga but thats just me.
Ranmaru Mori is obtained by completing the special requests by Mitsuhide and Ranmaru Mori in Survival Mode. they start at 1st floor i believe and the last one is on the 36th floor. if you do them all in order you unlock Ranmaru Mori.
both Okuni and Ranmaru have their 4th weapons in Survival Mode. neither have a Story Mode. Ranmaru's is obtained by defeating Keiji on the 50th floor through Keiji's Real Request on the 46th floor. Okuni's is obtained from the collecting temple donations quest by playing as Okuni. Okuni's appears randomly at the 60th floor and up I believe.
