SPAAAAAAAAACE!

The Tech-Priest communes with the local Machine Spirit and the room is repressurised; she runs a scan on the atmosphere pumped back in, just to be on the safe side, and doesn't let anyone out until it's complete. There's no abnormalities in the air, no strange pollutants or unrecognised toxins. Just normal ship air, carrying a faint tang of metal, oil and decay.

The group disembarks, Minerva in first, then Zee and the Gunners, then the Gunslinger. The Ratling is shown the way to the roof hatch, and together they can look around the docking bay. It's a cavernous room, with enough space for five shuttles like theirs, though there's only three present, and one isn't actually a shuttle- it's a Navy fighter, in very poor condition, partially stripped down to the point an exact identification of the model is impossible. There's other vehicles, too; some fork-lift trucks, mostly with actual wheels or tracks to simplify maintenance, but there's another Sentinel like the one that was on the shuttle they stole in Skyside (except I'm pretty sure they left it behind, since nobody has the training to pilot one). There's also a monorail set into the floor at the far end, with a small train upon it. There's two flatbed cars, a lift and a cab on the single line. All the doors are still sealed by thick airlocks, even the two used by the monorail.

The gunners follow Minerva and Zee, movements sure and disciplined. They've never fought Genestealers before, however, so they aren't checking as high as they should. The genestealer howls, an eerie and almost-but-not-quite-human sound, reverberating and echoing across the metal chamber. The gunners pan the room, not noticing as it scuttles across the top of the other shuttle, the one closest to where the heroes parked their own, and it leaps down almost unnoticed. Almost, however, but not quite. The Gunslinger pulls out a pair of massive revolvers and dives to the ground, shooting at the xenos beast, even as a single well-placed shot from the Ratling's laslock burns out its left eye. The Gunslinger's bullets bite into the monster's armoured carapace as it grabs the nearest mercenary and rips their face off even as the rest of the mercenary squad open fire. Even if Zee and Minerva don't join in, the thing's dead, and collapses, its victim on his knees and holding their face on with bloody hands. The flamethrower didn't join in, too scared he'd hit his mates.
