Free What Batman Arkham Item is this??

I remember Batman getting shot and he like stabs himself with a strange tube that sucks out the bullet and closes the wound? I can’t find anything about it as I didn’t play the game...

 

I don't think that was in the arkham games I don't remember that happening.

 

It is I just saw the entire trilogy, I think it was after he gets shot by Jason but idk if sucked his bullet or what but he did stab himself with something

 

I found it, some sorta syringe that he uses in justice league dark?idk man

 

Looks like an adrenalin shot or maybe something like bio-foam.

 

Crazy Glue.

It was originally designed for battlefield emergency sutures...
