'Just Cause' is set in the fictional Caribbean nation of San Esperito. The country has been taken over by a corrupt dictator. You play a CIA agent, working with rebel factions to destabilise the government and free the nation. It's a real sandbox title--there's a central storyline, but there's no real pressure to move it forward. Participate in a race here, lead an attack on a military base there: run guns to rebel cells, hijack helicopters, blow up coca fields belonging to rival drug-lords, or even just run around shooting everyone you see. It's like a marginally-less amoral GTA, with crazy-ass stunts thrown in for good measure. Damn good title.
