Ok, guys, this is my first NCIS fanfic, so bear with me. No flames please. Don't like, don't read, simple as that. Disclaimer: I do not own NCIS (the show not the unit, which I don't own either), or Bioshock. They belong to their respective owners.

Chapter 1: The Game

Special agent Anthony "Tony" DiNozzo strolled confidently into the lab of forensics specialist Abby Sciuto. Both Tony and Abby worked for the Naval Criminal Investigative Service or NCIS for short. It was a Saturday, which normally meant nothing to the head of the team, Leroy Jethro Gibbs, but for some reason, Gibbs had been in a good mood (which none of his team had questioned), and issued an "official" day-off, which translated to, "Do whatever you want, but you have to stay at work in case somebody gets murdered." So, Tony found himself taking the elevator down to Abby's lab that morning, a large Slurpy in one hand, and a cup of coffee in another.

"Aww, Tony, for me? You shouldn't have!" joked Abby, who was sitting in a chair holding a wireless game controller, and playing what looked to be a first-person shooter game on the Xbox 360, which was connected to a television set. Most of the team had the usual fondness for coffee in the morning, but while Gibbs preferred a special blend from Starbucks, Abby preferred Slurpies round the clock.

"Well, it is a day off…of sorts", replied Tony, setting the Slurpy on Abby's desk next to her. "Or at least until we hear those magic words, 'Dead marine, grab your gear.' By the way, Abbs, whatcha playin' there? I didn't know you had an Xbox."

"Oh yeah, it's this great new game I got last Christmas, along with the system. Since we're kinda locked in at work with nothing to do, I decided to bring it with me. It's called, 'Bioshock'. Basically, this guy called Andrew Ryan builds a city under the Atlantic, designed to be a utopia or something. But, y'know, there are rebels, and the whole city goes to hell, filled with these zombie-guys called Splicers…" Abby trailed on excitedly, like a teenage girl, despite her age, but Tony had stopped listening.

"What was that guy's name again, Abbs?" Tony asked, slowly and quietly.

"Andrew Ryan, why?" answered Abby, oblivious of any possible importance.

"I gotta go" was all Tony said as he ran out of the room and hurriedly boarded the elevator. Abby rolled her eyes before taking a big gulp of her Slurpy and going back to her game.

"That's why I don't drink coffee" Abby said to herself as she blasted splicers out of the way.
