Im not answering for him (whoever you asked that question to) but anyone who decides to speedrun any Onimusha game should definitely use Issens all the time.
I thought that. But, damn ... Issens are hellish techniques to do one after another (except of chain issens from triangle attack in Onimusha: Dawn of dreams). And You must wait for the attack ... this are the seconds, that in ~1h run are precious as ring to Gollum.
I just can't wait to see the run, and in the end to know the answer: only issens/issens if the situation is good/slash as soldier of Sparta and do not look at issens ...
i receive 2 message, one from "zareon" from 14august 07: he/she told me he is making a new onimusha warlords run i dont know its already done. he dont write back again
Lol! seems like the onimusha speed run might never get done. Maybe I will have to submit my 1:16 run JK! Check this out guys! I don't know why zero or Josh never submitted a run!? https://forum.speeddemosarchive.com/post/onimusha.html
I quit running the PS2 version due to not being able to skip cut-scenes. I moved to the Xbox version but haven't even started planning. It's totally different so it can't be compared to the PS2 version.
I think Joshkaz has a run in the works. I asked him about it recently but forgot what he said, I just know he has an insane time now. I'm sure he'll see this topic and reply.
