Pre-production work for "Far Cry 3" had reportedly started just after "Far Cry 2" was shipped, with plans to keep it as a narrative sequel, but in the few years that followed, many of the development leads for "Far Cry 2" left the studio. The project had a significant shift of locale, returning to a tropical island theme similar to "Far Cry" while retaining the open-world nature of "Far Cry 2". They also looked to keep the key elements of "Far Cry 2"s open world that worked but add in more features to make it feel like a living world but with purpose behind how they designed it. This led to the development of Dunia Engine 2 to implement some open-world features such as weather system, which premiered in "Far Cry 3". Several of the questionable gameplay elements of "Far Cry 2" were eliminated. Further, to make this world meaningful, they eliminated the multiple player-characters and instead provided one character that they could write a strong narrative around. Within "Far Cry 3", the player-character is part of a group of adventuring tourists caught by the pirate Vaas Montenegro who has tortured the island's native population. "Far Cry 3" was formally announced in 2011 and released in November 2012. Though "Far Cry 3" presented some controversial elements within its narrative, it still received positive reviews and had sold more than 10 million units by 2014.
