Monaco: What's Yours Is Mine is a 2013 stealth video game developed by Pocketwatch Games in which players, alone or cooperatively, perform heists and robberies. Players choose from eight characters, each of whom has a unique and beneficial skill, such as the ability to change appearance or tunnel through walls. Monaco's single-player story is told in four acts from perspectives of different characters. The cooperative mode lets up to four players play together in different locations.
