This was incredibly hard! I wouldn't recommend this challenge to anyone since the bosses in the DLC clearly weren't designed to get an S-rank on with Peashooter only. Took me way longer than I expected (exactly 300 attempts lol), but through pain and suffering (and with help of a God gamer Bufanda) we've completed it! It's time to do a DLC 100% run now!
