Aerith's level four limit break can be found in the blacksmith's house on the western continent. The house is near The broken reactor where you collect Titan, it's behind a mountain near the beach. To get the Limit you must give the blacksmith some Mithril. To do this take the buggy back to eastern continent by driving it into Cost de Sol and bribing the guard at the ship to let you stoaway. Once in Junon leave and drive into the forests to find a river you can cross. Go into the cave there and speak to the sleeping man, he'll give you your battle stats, if the last two numbers of your total battle count are the sam e.g 122 he'll wake up and give you the Mithril. Go back to the blacksmith and he'll let you choose the item from inside either a large wooden chest on the bottom floor (a gold armlet) or a small metal case upstairs (Great Gospel) go upstairs and take the Great Gospel.
Note: Great Gospel is a kind of compilation of Aerith's previous limits, it makes you invincible and heals and cures you. I can't remember if it puts up the other two characters limit meters but I doubt it.
PS. Mistah DEVIL your brother heard wrong you can't bring Aerith back to life in any way. The 1/32 on the toy soldiers stands for their scale not their total number.
I like the characters and how some change and some new ones are introduced and I like the gameplay, the battles are really interesting and good and it's a new way to battle that I had never experienced before.
Most of all I like the story line.
Putting all of this aside, I still can't manage to beat the big machine thing ( can't remember what it's called cause it's been so long since I have popped the game in and tried to beat the machine). I even bought the cheat thing, with the memory card and disk( yall know what I am talking about, it just recently came out last year I think). Well I used a cheat to make me invincible but when I get to the machine I am not invincible, I just have the highest HP you can have for all my characters and then the machine eventually usuall diminishes my HP and kills me. I still haven't put in my codes for some of the new skill outfits like dark knight and stuff like that. Maybe that'll work........i don't know....
P.S. Your answer is some where in there, lol, sorry.
You know what? You know WHAT?
The first game that should be made for PS3 is a Final Fantasy VII remake. I completely fell in love NOT with the game but the characters. They made the game. Cloud, Barret, Aeris, Tifa, Cid, Sephiroth--his psychoticness was SO damn pimp--hmm, the guy who could turn into monsters, and, my personal favorite...
RED XII.
