Getting 100% kills can be a little annoying. You need to wait in the center room and allow up to 7 Fiends to spawn about 30 seconds after each other (which means waiting for some time if you can kill them quickly). There is also a room which will respawn dead Scrags, these add up to 12, but at least you will be constantly fighting and the death of the previous doesn't leave you waiting. Overall, this level will spam you with enemies. I am surprised I left with as much Red Armor as I did, but I guess I did that due to getting it near the very end.
