I loved it. Pretty familiar, but we tried out one of the new missions using the tactical objectives. Absolutely great. Really made the game more interesting than kill each other or contest last minute and hope the game ends. I took a combined arms list of Lamenters primary with Sons of Medusa allies plus an Imperial Knight. Mephiston was a beat stick getting off Iron Arm plus Warp Speed almost every turn. Strength and Toughness 9, with 8 initiative 10 attacks! He would mow through whatever came near him.
We did play a bunch of stuff wrong I’m sure, but I’m feeling really positive about the addition as long as you have a nice conversation before hand on what kind of game you want to play.
