There's not much to the gameplay. You are a white or black androgynous person in the midst of a rioting mob, filled with people of the opposite shade. Your goal is to "talk" to the people who are highlighted and attempt to convert them to your point of view.
This conversation mode provides Gray's only actual gameplay. When you stop one of the rioters, an interface opens up. No, you will not be convincing this person using well-crafted arguments or a firm command of facts and figures. Instead, you simply wait for their signal to head your way, and you hit the [space bar] to send your own signal to meet it. Ideally they will meet in the middle, and if you get enough signals to meet, you will convert this person.
You keep doing this until you have converted the entire mob, at which point you change to the opposite color and start right back from the beginning. After a bit, a twist will be thrown your way. This twist is essentially what the game is all about, and so I won't ruin it for you.
