Bloodbath on Saturday night. We reached the heretic's landing site, which had defence turret and was near an excavation. They were cooperating with the xenos. We snuck down towards them, down a near cliff face which was only covered by the anti-air turret with the intent of launching a sneak attack. The armed lighter was there (closer to gun cutter than a lighter actually) and a small xenos vehicle.
We got close and the heretic started to leave. Surprise got blown by bad agility rolls and a spectacularly bad fall. I got to play with pyromancy, but the heretic continued to be far too fucking invulnerable. The xenos started opened up. I used float so I could do a running jump and then drop the 60 meters without dying horribly and landed on the lighter.
Meanwhile there was lases being shot at us from behind. At this point we were mostly wearing refurbished xeno armour. Our tech priest is from one of the those "take the xeno gear, reverse engineer and reconsecrate it and say its all cool" factions.
I take a bad las hit and drop down under cover of the lighter, setting people on fire who are in my way. I get in and engage in a close range and mercifully one sided fire fight with a guy with a bolter. I heal up and secure the command crew. The little ship gets away, containing the arch-heretic who escapes through the magic of GM fiat.
Meanwhile all hell is breaking loose. The IG is shooting people, the feral worlder is closing and the Arbitor is going close range, autopistol with manstopper rounds and power blade. Two xenos in power armour throw down and it's nasty.
The other psyker has gotten stuck in and is using psychic blade. He gets smooshed by a crazy hit from a giant shock maul and dies. Chainblades and all out attacks with power swords bring the power armour boys down. I get the weapon controls operating and the tech priest is taken prisoner by gas mask wearing human IG soldiers. Yes, we are the victims of friendly fire. From our GM's favorite WWI issue IG regiments, the Deathcorp of Krieg.
Things get sorted out, sort of. Tense stand off situation. That's how things end. Oh, and we have plenty of loot to buy shit. Too bad we aren't on a civilized planet.
