Have you played the PSP version? Found a newer patch version? Let me know in the comments – just keep it legal, friends.
First, I need to clarify that Warriors Orochi 3 was released for the PSP in Japan as "Samurai Warriors: Orochi 3," while the Western regions got a different title. However, there's a version on the PS3 called Warriors Orochi 3, which might include English language support. Wait, actually, the original PSP version of Warriors Orochi 3 in Japan was "Samurai Warriors: Orochi 3," whereas the PS3 version for the West was titled "Warriors Orochi 3" and released later with English. So maybe the user is mixing up the versions. The PSP version of the original game (Orochi 3) didn't have an English patch, but maybe there's a mod or patch for the PS3 version? But in the US/UK releases, the PS3 version might have been released in English. i--- Warriors Orochi 3 Psp Iso English Patch Free
