Kalypso Media declares today Tropico Day, marked by the release of a new T-Day DLC for Tropico 5 as well as a Steam Workshop update and sale for the island dictator sequel for Windows, OS X, and Linux. This page covers the sale, where games in the series are 65%-75% off. The patch brings Tropico 5 to version 1.10, adding five new maps, a map and mission editor, Steam Workshop support, and more. This announcement has all the details on the patch, and the T-Day DLC page outlines what it brings to the party:

There’s no business like show business! In his infinite wisdom, El Presidente has decided that our beloved island of Tropico is to be the leading cultural influence on the world stage. To do this, you will produce a blockbuster movie which outclasses every other Hollywood production in existence and sets itself up for endless reboots, sequels and director’s cuts in the process.

Every movie needs a set, and for this epic production, the whole island will be prepared for a blockbusting World War II movie. In ‘T-Day’, you must re-enact the defending of Tropico from its biggest-ever invasion and produce the greatest movie that the world has ever seen!
