No firm release had been set for Tropico 4; however, the Haemimont Games-developed title is promised to arrive within Q2 2011. The world-crafting, strategy title puts players back into the olive fatigues of the "iron-fisted ruler" of the small island of Tropico. This time, El Presidente must contend with enhanced political and economic systems while playing across new missions on new maps.

According to Kalypso, gameplay has been expanded with new political additions, "including more superpowers to negotiate with, along with the ability to elect ministers into power to help get your more controversial policies passed." Tropico 4 also adds new natural disasters, leaderboards, screenshots, and integration with social media staples Facebook and Twitter.

Key Features:

New campaign -- Face 20 new challenging missions across 10 entirely new maps

Build Your Vision of Island Perfection -- Not only are the graphics enhanced, but 20 new buildings including the stock exchange, shopping mall, aqua park and a mausoleum for El Presidente allow you to craft your perfect balance of beauty and economic efficiency
