All right, there's an achievement in Army of Two called "I wanna be a cleaner". The achievement is rewarded for "Final blow to Dalton is a headshot with a pimped .44 MODEL 29 handgun". Only problem is, you never fight Dalton, he's killed in a cut-scene. I've tried killing Clyde (the final boss) in the manner mentioned above, but nothing happened. Can anyone shed some light on this?

Regards, Aas.

You need the DLC.  I assume it's part of the challenge course you go through.
