Kalypso Media UK announces that Tropico 4 is now available in the U.K., offering the latest installment in this city-building/simulation game that puts players in the fatigues of El Presidente of an island republic. The game will be released in North America on Tuesday, a playable demo is available, and here's word:

Tropico 4 sees you return as El Presidente, the tyrannical (or benevolent) dictator of the island paradise of Tropico. The world is changing and Tropico is moving with the times – geographical powers rise and fall and the world market is dominated by new players with new demands and offers – and you, as El Presidente, face a whole new set of challenges. If you are to triumph over your naysayers you will need to gain as much support from your people as possible. Your decisions will shape the future of your nation, and more importantly, the size of your Swiss bank account.

Tropico 4 features all new missions across new maps and includes exciting and fun new features to keep the action fresh and challenging. You can even elect ministers into power to help get your more controversial decisions passed through the government. But remember to keep your friends close and your enemies closer as everyone has an agenda!
