US mobile games firm Factory Games has launched Valet Hustler, a game which aims to raise awareness about gay and lesbian marital rights.
The company is pitching the game (App Store link) as Tetris meets Diner Dash, offering 3D arcade puzzles around a virtual car valet business.
However, the two central characters - Ren and Akira - are both gay, with their sexuality central to the storyline as players progress through the game.
"We set out to not only create a game that is an absolute blast to play with incredible visuals and top notch audio, but we also wanted to make a social statement that gays and lesbians should have the same marital rights as heterosexuals," says CEO Andrew Littlefield.
A portion of the revenues from the 99-cent game will be donated to the Human Rights Campaign.
