The Imperial expedition was nearly wiped out in the ambush by Xeno forces, however, their dropship was able to get through to the Asteroid Colony and successfully land an elite squad of Space Marines to complete the mission.
The rules used for this scenario were Star Breach with the Legion of Mankind taking on the Hive Cult. I was testing the rule set and thought it would fit nicely with the campaign.
The Space Marines land near the generator and have to work their way through the winding tunnels of the asteroid.
The squad is deployed into the crammed quarters of their entry point with their leader, Amos, leading the charge.
Their target is the central computer that controls the asteroid communications, data storage and mining equipment. From this point they are hoping to deduce clues as to the fate of the colony and source of the Xeno threat.
The Miners have lined up to ambush the intruders, the Space Marines can see that these are no longer the industrious settlers that had set out but they have morphed in strange ways and their leader holds a banner of the Xeno worshiping cult.
There is no ambiguity about the Miner's intentions as they immediately launch a rocket at the intruders, the Marines were lucky to hit the dirt and allow their armour to absorb the impact.
A brute with a giant hammer follows this up with a charge against the nearest Marine, the exchange damages the Marine but he also manages to push the brute back.
Amos charges straight at the rocket launcher to cut him down before he can launch another salvo, his power sword makes quick work of the two Miners behind the barricades.
The Miners aren't fearful and throw a grenade at into the midst of the advancing Marines, the hurt Marine is taken out of action and the mech is also takes some damage.
But the damage isn't enough to stop the mech as he charges the grenade thrower and uses its crushing claws to take the miner out of action.
The Space Marines continue their advance, but are slowed down by a line gun that fires through the entire squad. The leader of the cult has developed psychic abilities which he uses to unleash a roar causing havoc among the Space marine ranks.
The Marines are elite soldiers for a reason, as they quickly recover and charge through to cut down the remaining Xeno lovers, eventually taking out the leader.
Amos makes his way to the computer terminal, downloads all of the historic data on the communications module and sends it back to through space for the Imperial relay stations and surviving ships to pick up.
As soon as the download and transmission is done, the Marines had back towards the extraction point. However, they hear noises coming from throughout the colony. There are more Miners than they had reckoned for and their escape path is covered with fresh enemy reinforcements.
The unsuspecting Marines are surrounded by more than double their number. While the data was transmitted successfully they were not heard from again..........
