Utterly Mad

I am amazed. A new RPG group i started playing with took over an ENTIRE HIVE WORLD whilst playing Black Crusade with just 2 characters. They fought and killed a Lictor which was supposed to take longer in the first encounter, one bisected a Genestealer Patriarch in one swing with a Mono Sword, Killed an Inquisitor and his retinue, which included a Vidicare assassin, Angry Marine, and Veteran Sister of Battle, Built a massive Fuck Off robot, Summoned a Lord Of Change, and killed the Governor Militant of the Imperial Guard in Two Turns.
And yet a single cop was able to nearly kill one of them, and remains the only thing to fight them and get away.
