BEFORE CRISIS -Final Fantasy VII-

[Ultimecia]

This isn't much HUD at the actual gameplay, really. Crisis Core plays exactly like Before Crisis (yeah, I had the chance to play it)

First you equip everything on the main menu (Equipment), from accessories and Materia. The icons are exactly the same as you have seem in all the other screenshots



The field got random battles, as usual. When you enter Battle Mode, there are some lettering like "Initiating Battle Mode" while a voice announces it. Every command materia you equipped is going to appear at the lower bottom of the screen, along with Attack and Item. You use the shoulder buttons to circle around then (L, R) and press X (or O at the Japanese one I believe, and "Enter" in Before Crisis) to do the action.
The DMW is a slot machine type, and if you got the right numbers you can get battle bonus, like infinite MP, infinite HP and so on. If you got two same characters (ie: Tifa and Tifa) the screen changes



And it continue spinning. You got the same character 3 times you got a limit break. The level of the limit is according to the numbers and you also get some healing for all (HP, MP, AP). If you got one odd character (example: 2 Genesis and one Aerith) then nothing will happen. The same bonuses you can get at the regular screen you can get here too. And if you get 7/7/7 and have enough experience you'll get a level up.
Each character grants you one exclusive limit break. If you don't know the character yet (only his/her shadow will appear), you'll get a generic limit break. There's also 3 limit breaks modes: characters, summons and chocobo mode.
The character one you'll see some old favorites limit breaks along with some small in-game animations telling a little bit of story, the summon you'll be granted with a CG (yup! CG during battle!) and chocobo mode you'll get a cute/funny animation. The only exception is for Genesis, it's like he "infects" the slots and changes one of the characters for his own, but otherwise it's like the regular ones

(above: an example of animation before Cloud's limit break (Meteor Shot), Aerith's limit (Healing Wave, grants full-cure and temporary invulnerability) , Ifrit's limit (Hellfire), Cait Sith's limit (from Chocobo Mode) (Courage Boost) and Genesis' limit (Apocalypse))

I guess it's cover much of the general gameplay
And sorry for the many images +_+
