I can't remember specifically if the team, towards, the end, made the specific assumption (in-dialog) that this was a bio-weapons facility or not. I have vague recollection of this, but can't be sure.
Captain Janek (to Shaw as she's donning her spacesuit and popping painkillers): "You know what this place is? Those 'Engineers'...this ain't their home. It's an installation. Maybe even military. Now, they put it out here in the middle of nowhere 'cuz they're not stupid enough to make weapons of mass destruction on their own doorstep. That's what all that shit
is in those vases. They made it here, it got out
...it turned on 'em. The End."
In the theatrical cut, it's the Zombie Fifield attack that leads Janek to this conclusion, combined with their disastrous second trip to the temple earlier that day and the mutation/death of Holloway. In the script (and possibly Director's Cut), the Fifield attack comes after this scene.
