Gamer Sense and Developer Shorthand

My Gamer sense is tingling!
So, you’ve just fought your way through hoards of powerful enemies. You may have wasted a lot of supplies, but you’ve made good headway into this dungeon. You open the next door, only to find an empty room, with naught but a save point and two gigantic doors. Oh lord; even though this may be your first time playing this game, you know what’s behind those doors. Yup, it’s going to be a boss fight.
