I had missed the official start of the campaign due to snow and then being out of town the following week, so this was the first mission I've been able to play. It was 1250pts, my Iron Warriors vs. Josh M's Grey Knights. The mission is called "Survivors", where the objectives represent injured warriors from the different factions you try to rescue/capture. After setup you roll to see if they are Imperial, Chaos, or local xenos (basically eldar). Objective for your faction is worth 2VP, opposing faction worth 3VP, xenos 1VP. Could make for some interesting late-game choices I think.
