What's really funny about this game is how you're a Chad, you're a big dicked kill 'em all expert. This game is the power fantasy simulator and you are the focus. You're the #1 shooter. You're every guy in a shooter ever. A real object of power fantasy. You're a special forces badass taking up mercenary work. Cue game start.
You're in the shower after an indeterminate amount of time, and stood staring at the wall as your ringtone goes off. It's an annoying ringtone. You stare at the wall a little longer not wanting to face the real world, then you go pick up your phone, while watching the carnage outside between "normal" people.
The call is presumably one of your few old friends, jokingly (but seriously) calling you a fucked up psycho who needs this handout from an equally fucked up hamplanet known as Handler and telling you that, yeah, you're the big boss player, but you're at the end of the line. You're both fuck ups, but this is your last chance, and welcome to the gig economy.
Empty Fuck is every FPS hero, but with a few years added on. He's fucking done. He can kill everyone, but he's already dead inside. He snapped before the plot even began, thus his discharge. I wouldn't even be surprised if after the end of Apartment Atrocity that CS just decided to fuck off trying to kill him for being a liability and sent him on more missions hoping he blew up in public instead, after offering him a pathetic excuse like fucking up the targets social security numbers for sending a hit squad after him. Eventually he blew up, killing off the global elites, gods and CS itself. He's Mr Power Fantasy, but is a totally insane spree killer equipped with all sorts of inhuman modifications. He is alone, empty, braindead, and sometime's faceless and lobotmized. The guy is fucked. Even Handler knows it.
If anyone played Brigador then he makes an appearance as MT Foxtrot and his lore text bemoans him as a man that is totally dead inside and will snap killing everyone within distance and that he should be sent somewhere else for everyone's safety, which actually happens in the story.
