The Japanese Incentive
Somewhere in between the meeting of his brother and the death of Louie Castaneda, Boss D'Angelo receives a lucrative offer from a Japanese Yakuza Hikaro Eda and Fritz, a backer who wanted to help Eda exert his influence into America as laws back then prohibited Asians from owning property. There he meets the beautiful Mikoto Mori, the trophy wife of the Yakuza boss. Little did the boss know, she has a personal vendetta against Hikaro and the Boss now is caught in between love for the woman and the wrath of a powerful man.
The story begins with Karl Fritz who approaches the Boss with a deal from Hikaro Eda, an influential Japanese man who had him muscle into McGyure Clan's turf and quickly proves his worth to Hikaro and was tasked with a smuggling job from him. Upon preventing the McGyure Clan from destroying the cargo did he realize what was he smuggling, his wife Kumiko Mori. Angered by the McGyure's attempt at murdering her he personally wipes out the clan and earns a promising alliance with the Yakuza. When Hikaro and his men were attacked at a Cherry Blossom festival by members of the Ku Klux Klan did Hikaro sent him to find who tried to kill him and the Boss learned that Hikaro's own wife was the culprit. Sickened by this senseless conflict he tries to run off with her in an attempt to escape from the criminal underworld only to be dragged down by Hikaro when he tries to kill them both. Then she reveals her past, her family's lands was taken away by Eda and her sister was killed by Hikaro and she was forced to become the bride and assassin of Hikaro. They both work together to take down Eda and eventually have feelings for one another but the heist on Eda's personal assets goes awry when Mikoto goes off to try and kill Eda only to die in the process, in a fit of rage the Boss personally attacks Eda and gets his revenge for Mikoto as he bitterly says that she was the first and last woman he had ever truly loved.
Trivia
Omerta, the game's title, refers to the infamous honor code called "Omertà", a "Code of silence" which binds members of the Mafia or similar criminal organizations to professional discretion against any third parties.
Upon the official retail-release of the boxed- and digital distributed version, the game was also simultaneously released on GOG.com without any copy-protection, nor other digital rights management restrictions.
Gameplay
Beginning with small deals, the player gradually expands his criminal career, eventually advancing highly enough to establish his own business. The player can purchase untenanted shops, buildings and structures to establish his own bar, brewery or distillery. The player can also buy out an opposing speakeasy. A more legal way for generating income is buying apartments to obtain leasing. Warehouses can be acquired to extend storage.
As the game progresses, the character can recruit companions, create his own gang, and conquer the territories of rival gangsters. Characters provide specific role-playing elements based on their individual characteristics and equipment. In these turn-based confrontations, the player expands his influence by using henchmen to drive other godfathers out of business, to ultimately reign supreme as the unchallenged patron of Atlantic City.
In addition to co-operative and competitive multiplayer game-play, the game offers a sandbox mode to freely explore the game world – six district maps covering Atlantic City.
Historical background
The game provides an explorable three-dimensional world which is displayed through a Top-down perspective. The in-game world represents, according to the publisher Kalypso Media, an almost accurate and historical correct reproduction of the American city Atlantic City of this period.
Real vintage buildings and places are present like the Traymore Hotel, the Absecon Lighthouse, the Atlantic City Jail-house or the board-walk "Eastern Promenade" as well as streets like Illinois Avenue or the North Carolina Avenue which ends at the beach. Beside those real buildings the remaining ones - which are shown in Art Deco - are very similar to each other and seems to consist only of a few types.
