Gabe Newell and ZUN go out to lunch for a business meeting. Between Gabe's food orders and ZUN's drinks, they would have to develop Left4Gensokyo to make up for losses.
Uh, all three mages are there...more like 5000 bullets (alice, patch, reimu) and a huge laser blast at a time.

Or for that matter, since faeries technically can't die permanently, she could just go and capture Cirno...
