In left 4 dead 2, there's currently a mutation called Four Swordsmen, where you can only use a sword to play the level.
I was wondering if finishing a level would award me the Confederacy Of Crunches achievement (Finish a campaign using only melee weapons).
I ask because there are no common infected on this mutation, so perhaps it doesn't count towards it, being different to a "normal" campaign.

As far as I know, it should count towards the normal campaign. My friends and I have played the mutations every week so far. The first week, we were all able to get the achievement for crossing the bridge in under 3 minutes in The Parish because there wasn't a full number of common infected. We also all received credit for chainsaw kills during the chainsaw event, so I presume that you should be able to get full credit for Confederacy of Crunches.
