It's a last man standing battle between Jill and Nemesis, since there is no way out, just after Nicholai's death in the non-canon version. I suppose that the circumstances are almost the same in the canon version of this battle but I haven't tried it. What I wanted to ask though is how you deafeated him. The introduction shows Jill evading Nemesis's attacks which hit the pipes insted. This makes the pipes spit some kind of liquid which does massive damage to Nemesis. During the fight I tried myself dodging his attacks but I failed. Can he hit the pipes like in the beginning? Also I tried shooting the pipes but he would always step back and get away as the whole procedure was too slow to hurt him. After this I didn't bother much with the pipes because I had around 50 magnum rounds..
