Atom Grrrl!! features same-gender relationships between women. It is designed to be deliberately offensive, potentially attempting to use dark and crude humour, but instead simply being racist, sexist, and homophobic. The game relies heavily on expletives, uses sexual assault as a punchline, and has just about every trigger warning possible attached to it.
