The reason both parts will be released completely for free is that the game serves as an advertisement for the 150-year anniversary of the insurance company Swiss Re. The game will not be cluttered with ads for the insurance company, however, as the only branding in the game is said to be the Swiss Re logo in the game's credits.
The exploration of risk throughout the gameplay itself and the game's storyline serve as the advertisement. The game is said to contain a "special gameplay mechanic that reveals a hidden matrix of cause and effect". And you will "command the fates of thousands by mastering a hidden technology that gives the player the ability to foresee risk."Both parts will contain between 2 to 3 hours of gameplay, and both parts will be released for iPad before the end of the year. The first part is scheduled for release this October, and second part is expected to be released some time before the end of this year.
