Okay it is not my group but a GM I know who running a Dark Heresy Group for 4 players (Arbite, Cleric, Guardwoman, & Adept) rank 5/6 operating for the 1st time fully undercover, not overt members of the Inquistion.
While operating in new planet "think like Wild West", investigating Smugglers, the team endup staying in hotel in a small village while waiting to travel farther inland overnight. They had a few drinks with supper in the bar and then went to bed.
Unknowning that the a gang had decided these travelers well, were ripe for a robbery/murder. 2 team of 3 mook gunslingers (1 armed with sledgehammer and revolver, 2 with a pump action shotgun and revolver, 3 armed with a revolver) line up on each door to the rooms they are staying in back by 1 "experienced gunslinger" with a SMG and a revolver. Not that this group should really be a challenge for these 4, but they never posted a Watch, so the 1st clue they had anything was wrong was sledgehammer hitting the door lock and then the shotgunner slamfiring the shotgun into the room. Had 1 door not taken 2 sledgehammer swings to open, we might be talking party kill (as the Arbite and the Cleric were caught by surprise in that room for 1 round).
Okay so what group of experienced players doesn't keep watch at night????
End result
Guardwoman shot twice once from shotgun in the left leg, right arm by revolver
Adept shot in the chest by revolver and in right leg (trying to stop the bleeding)
Arbite shot twice by shotgun 1 body other head (min damage)
Cleric shot once in Head by Shotgun still kinda functional, revolver to head (blew a fate point to avoid death)
Guardwoman with autopistol on full auto dropped most of the team hitting her room
Adept got 1 hit with heavy pistol he had into a mook head
Cleric drew his pistol hit nothing
Arbite grabbed his combat shotgun and blew away the team hitting his room and then made to to the hallway to asssit the next room
