This year my club (Wellington Warlords) is going to run a Kill Team Campaign, and so we have resurrected our old campaign that we ran from 3rd edition until it petered out in 5th or so.

It was not a campaign in the sense that we had maps etc, although occasionally we did map campaigns. But more that we used stories to link the battles. The armies in our area knew each other and the characters became larger than life, with feuds and backstory over many many games.
