Akumu update:
Ch. 3: The Ruvik clone was pathetic once I got him alone, hit him with a harpoon, then lit him up with a match on the ground. Mr. Chainsaw didn't move fast enough to escape repeated spear-trap-springing in that one house, so he died in less than a minute. Why did it take 5 playthroughs to have the easiest fight against him?
Ch. 4: The Incendiary Bolt from the Fighting Chance Pack is so OP, as it made the end-of-chapter arena fight a cakewalk due to the funneling enemies.
Ch. 5: I think I lucked out with a glitch while fighting Laura, as she died from being burned only 3 times (the third time with the big furnace you activate with a lever), despite surviving those same 3 burns on previous runs.
Ch. 6 (beginning): Velo, you might not believe this, but I got past the burning house within 20 minutes. I probably used the absolute cheapest strategy ever to do it, though--waiting for the enemies to cluster together then spamming 16-second-lasting Flash Bolts over and over and over and over until Joseph unlocked the doors. I started the section with 20+ spare parts, and now I have 8 or so, I think.
I stopped for the night immediately after that part since my hands were still kind of shaky. From what I've heard, the rest of Akumu should be much easier.
