I looked at a guide for my secret ending playthrough, which was also the last one I did. No way I could have done it otherwise.

I'm actually putting a wrap on my playthrough of Midnight Suns, because the Megaman Battle Network collection just came out and has enthralled me more than I expected. So I'll probably replay Midnight Suns when the season pass goes on sale and I can get all the DLC at once. I'm looking forward to that.
