Producer Chris Busse explains how Medal of Honor: Airborne's "start anywhere" functionality lets the player choose the course of each battle.
From the diary:
"With the 'start anywhere' feature in Medal of Honor: Airborne, you no longer fade up from black or out of a cut scene at the start of a level. Nor do you run along a rail to the final objective; you choose where to begin your experience. Even more importantly, if you are curious about what might have happened had you started somewhere else in the operation, you can jump again and choose a new starting location…and again, and again, and again."
