The basic scenario is, The Genestaeler cult has revealed itself and the planet is in chaos. The Capital city is firmly in the Cult's hands but they have a weakness. The Capital's only water supply is a massive cistern in the mountains lightly held by Cultists. The Rogue trader has directed a detachment of his forces to capture or destroy the wellhead, eliminating any resistance.
As the Imperials mobilize the local Magus sends out a telepathic signal and dozens of cultist and mutants rally to defend the wellhead.
The Rogue Trader Detachment. Two Dreadnoughts, Two Imperial Dick marine squads and a Heavy weapon squad, a Rapier laser destroyer, two thudd guns, two Imperial army squads and a Squat close combat specialist squad. This is just above a Two Thousand point army. One note on the marine heavy weapon squad is that every marine but one has a heavy weapon, a big difference from the more modern devastator squad.
The Imperials advance into the settlement.
Three beastmen finally make it into hand to hand.
The frenzied Brood brother charge into the Marine heavy weapon squad.
After some rereading of the vehicle damage rules the first limo is destroyed instead of shrugging off repeated hits of muiti melta fire. Knowing their time is short the Patriarch and pure breed genestealer get out and charge the dreadnought. They proceed to bounce all their attacks off of its power field.
More Beastmen join in the assault with the frenzied Brood brothers.
bombs. This is the most 1 1/2 inch radius templates Chuckaroo and I have ever seen used at one time.
The Third mutant bomb goes off in a good fireworks display but causes no more collateral damage.
