Help I'm stuck. I have no weapons, he jumps around throwing grenades at me. At first he only throws 1, which I can breach, but at one point he either just throws 4-5 which I don't have time to breach all of, and kills me, or he throws this gadget on the ground, followed by 4-5 grenades, which also kills me. What am I doing wrong here? Am I supposed to go somewhere, or get a weapon somehow? Dying 6-7 times is not fun.
