You're walking through the snowy streets and derelict buildings of Copper-9's abandoned city, you then see and hear a huge explosion and some maniacal laughter coming from the site, being curious, you go over to see a Disassembly Drone laughing like a crazy person... which they all actually are somewhat... and she then throws a grenade into the air and watches it explode, she then laughs some more until she turns around to grab another explosive and she notices you.

"Ooooooh! Target practice!"
