I say they're from Isolation because they're basically using the same models (Amanda was never released as a full model in the game, but I've seen the player model myself). The Alien is identical, I assume Amanda is too. Anyway, here's Ellen from the Aliens table and Amanda from the Isolation table! Ripped, so no bones, but I know that if you have Isolation, Amanda's skeleton IS there in the game and can probably be used as a model for this...
