I don't know if anyone else has made this comparison, but Act 3 of this game is like if MGSV continued after the wild fucking reveal ending and you actually got to play through Big Boss' Outer Heaven arc in Chapter 3. I'm playing through the game for the second time, this time with English VA, and I'm glad that I played through the first time in French because one of Maelle's battle lines (let's spill some ink) really gives away far too much about the world that is revealed in the end
Also, I don't know why I decided to waste my time beating this boss early instead of just coming back at a higher level, but here is the proof that I did.
