The only mention of rape comes from a character named Cait. She was mistreated by her parents and then sold as an adult. She was prostituted by her owners until she bought her freedom. She started fighting in an arena until raiders seized the arena. The leader of the raiders handed her over to his men because she refused to sleep with him. There is no other mention of rape in the game. Another detail is that Cait's appearance is inspired by Shepard and she has a life similar to Jack's life, two characters from Mass Effect. The character could be an insulting message sent to Mass Effect.
