We usually starts our game day with one round of Death Angel. But I for one thinks that more Location cards is needed and more of a threat. We win four out of five times.
I've have toyed with the thought of adding a Patriarch, Genestealer Hybrids & Magus. Since they can be found in the old editions of Space Hulk, and I for one would really like it to be a feature in future expansions of this incredible addicting game.
