Does that mean it won't work if I get the model from an older version?

Well, that would probably make no difference. It's the same model.
The animations don't work just by being in the model, they have to be activated through the game code.
So, unless a dev codes it in, there's no way to get a death animation, because the model simply disappears when the hive goes down.
