pretty pleased with my end result too. I wanted to give up at 9F because of a stupid ass mistake that cost me full marks on the missions.
then in the end, I managed to clear it all with some uhh persuasion and help from my friends... only had one shot at 15F, tho, and had NO thunder himes left... going in blind again I got her to about 20% HP before I kicked the bucket. Didn't actually plan for 15F tho, so it's all good...

GZ to all who beat it I hope you get better soon, Slashley.
