I hate to use my daily "Um, ackshully" on the AvP movie of all things, but it wasn't a room full of Facehuggers. There was that sacrificial chamber of Facehuggers, but that was before the scene with Scar, and only involved humans. He killed a Facehugger, then a Xeno, then took his mask off to mark himself as having completed the ritual, then got ambushed by another Facehugger before he put his mask back on. A truly bonkers sentence, and I suppose one could argue it was a
temple, not a
room, that happened to have a
handful of Facehuggers running around, but the distinction is noteworthy.
