Rosika is the first of the extra multiplayer characters unlocked with the unused cheat option or button code. She uses the same head as the Marion character, but her body is unique: it is a variation on the female scientist, with the unflattering filename CfattechwomanZ. She's shorter and, as pointed out by the filename, a little fatter than the scientist, and wears short sleeves, sheer pantyhose and a different style of white shoes.
