"Level 22" is not a glamorous name. It’s generic. It doesn’t inspire excitement. Without context, it could mean practically anything. So it’s the perfect way to reference a floor of an equally generic corporate tower, which also happens to be where you work. The trouble here is that it’s a weekday, and after a night of heavy celebrating for your birthday, you’re not at your desk. If the boss finds out you’re late, you’re fired. How do you keep your job? If you’re a fan of Hideo Kojima’s classic, quirky stealth-action series, Metal Gear Solid, you probably already know that your only recourse is to sneak all the way back up to your desk on the 22nd floor through increasingly complex scenarios.
