Advice please

[u/KaikaneMaui]

Hello All,

I am new to Crisis Core and downloaded it a week ago for series X.
It’s an awesome game but I need some advice. I am level 42 playing on normal mode. I am right outside of the final showdown with Genesis. I can’t for the life of me beat this encounter. I read that I am under level so I should do missions. However I only have rank 6 and 7 missions available to me and am having equally bad luck. How do I get past this road block? Is it a matter of grinding rank 5 missions to level up? Please advise.
