Has anyone EVER got a full star rating after a fight in SW '13? It's hard, almost too hard.
I've used normal sword attacks, Ki loaded attacks, dark power attacks, used demon weapons and normal weapons.
Never gotten a full star rating. Once, just once, I was a half star away.

I did couple of times, it seem influence by several factors: how many enemies you take in a single shot (for example by rocket launcher), special katana attacks, how much damage did the enemy cause you.

Only you answer my posts, I'm so glad. :D
But yeah, that might the case. I said I tried everything, but I mostly play with just the Kage blade.
Every other weapon feels so lacking. SW '13 is total opposite from SW '97, where you almost never used your sword.

Yea, the katana is the most fun weapon to use, especially after upgrading it with special attack, I also like the rocket launcher - again awesome weapon after you upgrade the explosive range and allow it to fire three rockets at once.

Can you upgrade the sword? Or do you mean when getting the second and third blade?

Yes, when you get the second and third blades they add new abilities to your katana.

The life sucking power is almost key to survival on later levels, good thing it comes so late for just that same reason.

I kept all my money and fully upgraded the rocket launcher. It still sucked.
For close quarters I use the sword, for flying or other kinds of distance enemies, I use twin uzi's.

Yea, the rocket launcher isn't very effective against airborne targets, they move too fast. I usually use it against the big demons, I also like to creep to unsuspecting demons and blast them with rockets.
