It was a bloody fight between the (mostly) Black Legion and a Blood Angels Successor Chapter, the Angels Encarmine. Sector A1 of the Oteck Hivesprawl was deserted, and the armies would soon learn why.
I played an Actual Game! And I got to use my Realm of Battle Sector Imperialis board.
We played with the Genestealer Infestation rules from the Vigilus campaign book, and let me tell you, them Blood Angels just got madder after fighting though them.
We used a mission from Chapter Approved 2018, with 5 objectives and earning victory points each turn.
It was a good game.
