Well, I don't have pics or vids to post, but I can definitely say that, if you are looking for a good UMK3 experience that is portable, look elsewhere. This game, while it does actually look kinda cool, does very little to actually recreate the feeling of UMK3.
The virtual stick and buttons are very poor and moves don't come out consistently... you feel as if you're fighting the controls and not the game. Auto combos don't work well...some hits that should connect actually miss. This could have been so much better.
Currently, the game only has 9 characters and 2 "?" boxes that are not selectable.
Current charcters are:
Unmasked Sub-Zero
Scorpion
Kitana
Nightwolf
Jax
Sheeva
Sonya
Liu Kang
Stryker
While the new 3d look to the characters is kinda cool, they game just doesn't perform right. As I said, the virtual controls are just way off. There are 2 control styles, a one with a Block, Run, Punch, Kick and Special button... the other is the standard 6 button HP, LP, HK, LK, BL, Run and you can theoretically configure them, but the problem is that they buttons don't always stay where you want them to move to.
One kinda cool thing that's new is that all the characters have a small "intro" before starting the fight...they all do their win pose right before starting the fight.
In terms of bugs, I have already noticed that if you do Scorpion's teleport punch, it can sometimes cause the screen to stop scrolling until you perform another teleport punch which will bring the screen back to focus on the fighters and begin scrolling with them again... it's very disorienting and you can be fighting completely off the screen and have no idea what's going on when this happens.
Overall, if you're looking for UMK3 on the go, stick to the DS version.
