Kalypso Media announces that Tropico 5 now supports SteamOS and OS X, expanding El Presidente's dictatorship to even more systems, all of which can play together. This is available through Steam or the Mac App Store. Here's the deal:

This just in from the Tropican Department of Information: Tropico 5 is now available for Mac & SteamOS via Steam! Starting today, Mac & SteamOS users can now visit the island paradise of Tropico in the award-winning dictator simulation Tropico 5. Embrace your inner dictator and begin your dynastic rule as El Presidente, carefully plotting, coercing and glad-handing your way to complete control of the Tropican isle, all while laying the framework of continued rule through the Eras with the all-new Dynasty System. Take a break from the everyday rigours of dictatorship to increase your wealth and influence by building farms, rigging elections, or dabbling in international trade. While the despotic possibilities are endless, so is the humour in the fifth instalment of the Tropico series.

The Mac/SteamOS Steam versions feature cross-platform multiplayer via SteamPlay, as well as Full Controller and Big Picture Mode support. Plus, if you've already bought Tropico 5 on Windows for Steam, then you can download the Mac/SteamOS edition for absolutely free via Steam cross-buy! For console players, Tropico 5 will be available for the Xbox 360® this November, and the PlayStation®4 version will be coming in early 2015.
