A new game developed at Carnegie Mellon University aims to change the way people react when they witness sexual harassment and violence.

The game is called Decisions That Matter, and it follows a group of college-age friends on the night of a party. Along the way, members of the group face a number of challenges and uncomfortable situations that people of all ages might find themselves in every day, ranging from street harassment to unwelcome advances from a stranger or friend.

In each situation involving harassment or assault, the player must choose how to react.
