By running out of hp.
Zack is 16 when Crisis Core begins and at the end he is 23.
Zack died in the outskirts of Midgar.
Sadly, in Crisis Core you can only control Zack in the game. Crisis Core seems to break the Final Fantasy mold and unlike Final Fantasy VII, the game is completely centered around the main character.
Zack dies, unfortunately. :(
Zack is voiced by Kenichi Suzumura in Japanese and Rick Gomez in English
Zack is the only playable character in Crisis Core, so you're stuck with him from start to finish.
no, its a video game for the playstation portable
There is no Crisis Core movie but the film Last Order: Final Fantasy 7 follows the same idea (Zack and Cloud ect.)
Sadly, no. You can only use Zack Fair.
No. In the end of Crisis Core: final fantasy vii (7) Zack meets cloud story continues and the last chapter of the video game Zack dies. Saying that cloud becomes his "living legacy" then passes angeal's / Zack's buster sword. In conclusion.... no Zack is not clouds father, even though they look similar.
Yes and you can find more about it if you play the PSP game Final Fantasy VII Crisis Core
His full name is Zack Fair.
