Nadine — Abby Winters

Wait, Dead Space does have a character named Isaac Clarke, who works on the ship USG Ishimura. The crew includes several characters like Isaac, Nolan Stil, and others. But I don't remember a Nadine in the main cast. Maybe the user is thinking of another role-playing scenario or fan fiction? Alternatively, could it be a typo for Nadia? Or perhaps they're from a different franchise?
