Battle of Canopolis

"Well, it looks like Canopolis is facing a new threat; the Strategic Orbital Linear Gun. I bet we're ready to save the city, and it's gonna be Operation Arcadia all over again. If it gets destroyed, then Canopolis is gonna be the next Hiroshima... and/or the next Nagasaki. Can also be Chernobyl, Fukushima, Guam, Hawaii, I don't know. Hope it won't happen. We'll do our best."

--Su Ji-Hoon, Doing Their Best
