Give your island paradise even more character and name your inhabitants freely according to your wishes!

'FESTIVAL' DLC LAUNCHES FOR TROPICO 6

We have today thrown open the doors for Tropico 6’s preeminent presidential party – the brand-new Festival DLC. Starting today, PC players (Windows, Linux, and Mac) are invited to host the biggest bonanza the archipelago has ever seen, presiding over its planning and working closely with El Presidente to fight for their right to party.

Tropico 6 – Festival challenges players to channel their creativity by planning and managing a series of celebrations, while combating ‘The Boredom’ – an evil, fun-fighting force that threatens to thwart all festivities on the sun-soaked isles of Tropico.

Empowering players to serve up the best soirees possible, Tropico 6 – Festival also adds a unique party planning mechanic to Tropico 6, allowing players to host 20+ types of festivals. Four distinctive, themed areas will be included for players to throw spectacular shindigs, as well as new buildings such as the Dance School, Balloon and Fireworks factory to get the party started. Players will also be able to enjoy a host of new musical additions, alongside a snazzy party outfit for El Prez and a paint job for the presidential palace.
