I finally killed Pater and Hawkins, I spent 2 days trying.
I'll say, I'm not the best player at this, but I've managed by modifying my ACs and using different equipment depending on the opponents, but these guys were the worst, especially because it seemed like the flatwell was only dying out.
This was the first time I used the flamethrowers. I remembered that the enemy who used them could easily throw me off balance if I wasn't careful, so I decided to use them against Pater, who doesn't have the best balance.I succeeded on my first try using both the flamethrower and the quadrupedal legs.
Additional note: I probably misspelled some names, I don't know the correct English names, and others I just forgot.
