I pretty much just push the punch and kick buttons and somehow get some occasional combos off. I was doing ok till i hit an opponent in the story who i'm assuming is sorta a Boss and he kills me everytime without a challenge. So my question for those with experience is how complex is it to learn some moves and combos and get decent with the game? I realize it takes practice but if it means learning a 10 key sequence then i think i'm over my head.
K, Xmann, here's what you do.
Up, Up, Down, Down, Left, Right, Left, Right, B, A, Select, Start.
no, wait, that might be wrong....
Go into the practice mode, and choose a character you want to learn. Once you're in the dummy mode (where you can punch and kick an opponent) hit start, and in the menu there should be a "training" or "practice" option (I don't remember offhand which one it is). Also note that in standard battles you can always pause and see the complete moves list too.
They will take you through EVERY move the character has. Just note that some moves (only 3 or 4 of them) where they indicate a direction, you need to be coming OUT of that direction. (for instance, if it says down, X, X, Y they may want you to crouch FIRST, and then as you let go and are STANDING UP you hit X, X, Y).
Unlike Tekken, the moves in DOA:U aren't like programming a 15 string combo. The longest combo in the game is Ryu Hyubasa's spinning upside-down piledriver move, most of which is full-circle moves (so the string would be up, upright, right, rightdown, down, downleft, left, left up etc etc..)
Each character has a training mode, and some of the training modes may unlock costumes or characters (it's been a while since I played it).
