If building plantations, starting trade, and even working on a space program weren't enough for you, then Tropico 4 players should be hppy with the announcement of the next DLC pack for the game.
Megalopolis will seemingly continue the spirit of the Modern Times expansion in a sense, because the new DLc is centered around cities. As in building and managing them. You have immigrants arriving and more on the way, so the new Conventillo, a massive, shoddy, yet cheap housing structure is one of the solutions at your disposal. There's the new trait, Beaurocrat, which lets you use the new building permit to build cheap buildings and pocket more for yourself.
There's a new campaign included, with the mission Megalopolis, and a new fancy dress Mayor outfit for male avatars. This DLC will be compatible with both the standard and the Gold editions of Tropico 4. It is available now for PC and will arrive sometime later this year for the Xbox 360 edition.
