Pit Viper was an okay character in the original Twisted Metal.
Not the greatest vehicle in the game but a decent ride.
Her official ending and her lost ending are very similar but with one key difference. She was hired by the Los Angeles community to take out Calypso. She distracts him with some with a million dollar request while she takes her shot. In the official ending, she successful at ending his life. In the Lost Ending, Calypso manages to escape and while she’s distracted, he sneaks into her car and returns the favor.
