Is there another path to the credits or is something whack with the stats?

Beat story mode on easy tonight and noticed the achievement for "Credits Reached" has a 7.6% completion rate among the player base... Meanwhile unlocking chapter four is on 6.5%.

Is there another path to the credits outside the main story missions?

Oh, and btw... Stellar friggin game. Huge Goldeneye fan here and THIS is the sequel I always wanted. Moreso than Perfect Dark or any of the other Bond games over the years... Just, congrats and heartful thanks to the developer... What a fantastic thing you've achieved here!

I played with my friend in co-op mode. This did not unlock the challenge for unlocking chapter 4, but we were able to unlock the achievement for "Credits Reached." I guess many people are playing with friends perhaps.
