Could you tell me what methods you use to exploit the ai? I haven't invested much time into the actual gameplay of doa honestly and I'd appreciate the help unlocking costumes as I can't even unlock a third costume for some characters.
All I know is there's throws, basic attacks, and holds and each one beats another one. In addition you have various heights of attacks to prevent block and hold spamming. This doesn't help me at all since I don't know the movesets and the AI just spams holds and blocks because it reacts perfectly and instantly, which I can't do because I don't know movesets and which hold/block to use for which attacks.
I don't understand the difficulty in these games. It seems like anyone who has actually learned movesets before easily rolls through any difficulty, and people like me who haven't played much at all get fucked at anything above rookie. Game difficulty is one of those things that I've raged about on these forums before: I don't want to invest hours into learning gameplay for a game I really just bought as ryona entertainment.
I use Hayabusa. He has a stance he can go into by pressing Down and P+K together. While in this stance, I use Up and K to do a diving kick. Most of the time, it'll connect. I spam this when I have some distance between the opponent and I. They'll occasionally do a hold on it, but it isn't common.
Some other pointers: don't use holds. Just don't bother. The timing is precise in this one and you're viable to make mistakes. Mis-timing holds can lead to even greater punishment. Only ever use them if you know for a fact that you can pull them off.
My best advice is to go through Command Training in Training mode and learn some characters' moves. Find someone you're comfortable with and try to learn attacks that you think will be useful. I prefer to use quick, easy to learn combos and to use them in a variety on top of my spamming method. This keeps the A.I. guessing. There is an air of luck about it, as some A.I can get downright nasty with their holds, but pay attention to what attacks their using holds on. If they keep holding the same attacks, you may want to stop using it and switch to some different attacks. Also, once you get an opponent airborne, hit them with everything you've got. They're the most vulnerable when airborne, as they can't hold anything. Power Blows can also be useful to turn the tide when you feel you have a window to use it. I've found that the A.I has a hard time countering them.
On another note, I just did every Time Attack path, but the Trophy didn't pop. I'm kinda peeved right now.
EDIT: Oops. I just realized I don't even have the Arcade Master Trophy, either, and it's because I didn't do the Tag matches. Now I feel dumb lol.
