Omerta is a strategic massively multiplayer online role playing game where players undertake criminal activities to earn money and experience.

Once their family has risen to a certain level of power and stability, the player can expand into illegal rackets such as managing gambling clubs, reselling booze, and even drug dealing.

When setting up their account, the player can choose to either start in a city of the United States or Italy, where the Mafia has deep and lasting roots.

Another possible location is Las Vegas, where players can try their luck in mob-run casinos which offer a wide range of slot machines, black-jack games, and even roulette tables.

Families are extremely paranoid and suspicious of each other, and if the player attacks their members, tries to take over their rackets, or infringes on their territory, they will be more than happy to go to war.

Players have a number of options to protect themselves from rival families: they can hire bodyguards, purchase getaway cars for a quick escape if attacked, and even wear special "bulletproof" suits.

Omerta is a pioneer of free-to-play games;[4] it does not carry banners or other advertisements and there are no exclusively-paid functions which would give paying-players advantages over those who cannot.
