Kalypso has finalised the Tropico 4 release dates as 26th August on PC and mid-September on Xbox 360.
Tropico 4 folds in Twitter and Facebook support. It also enables you to elect ministers into key positions to ensure controversial decisions get the green light.
Tropico casts you as El Presidente, the nice or nasty dictator of the eponymous island paradise.
A Tropico 4 demo is available to try now.
Eurogamer turned up an 8/10 in its Tropico 3 review in 2009.
