hammer

I was traveling along and i got hit with a missile launch which took a chunk out of my health. So i go to switch to my weapon and i didn't have any. Just my Immersive breaker breaker because i left without grabbing my stuff.... (I was trying to find the problem plot) Anyway i couldn't run cause...

I was wondering how does one get the IBB Hamer to upgrade, I've ben looking but haven't found sqwat on it but it says I can use it to upgrade, is it possible it's only for you king or do we all get the mighty hammer?
