Going deeper down the fox hole (yes, it's called a mixed metaphor), Infinity Ward checked specific data on certain levels:
- 71.1%, or 7,111,508 people have completed F.N.G.
- 68.8%, or 6,886,509 people have completed Cargo Ship.
- 46.5%, or 5,654,643 people have beaten the game on any difficulty.
- 2.8%, or 283,632 people have completed Airplane on Veteran difficulty.
Comparatively, pulling the multiplayer numbers from PSN revealed 4,381,276 unique users. Now we just want to know how many tries it took that 2.8% to complete Airplane on Veteran.
