Her “final girl” status is definitely a horror trope. But her path to survival is rooted in her compassion and comradery. This sets her apart from the male cast, who embody a more traditional masculine frontier stereotype that ironically fail to serve them on The Final Frontier.
From wiki, since , again, I haven't watch alien in forever.

The remaining crew decide to initiate the self-destruct sequence and escape in the shuttle, but the alien kills Parker and Lambert as they gather supplies. Now alone, Ripley starts the sequence but the alien blocks her path to the shuttle. After trying unsuccessfully to abort the self-destruct, she reaches the shuttle with Jones and launches it before the Nostromo explodes.
Now, this shows there's 1) another woman who also dies, and 2) another man in the same situation as the women.
Part of this that I find kinda annoying is that we're basing these things off "traditional assignments" on what "masculinity" and "femininity" are, which as we are finding out (and have been finding out through feminism) is fucking bullshit. Men and women embody various roles and archetypes, and have done forever.
