It's awesome! A must-buy. No offense to Gamespot but they underrated Just Cause 2.
The first and second missions are a bit hard but after that you enter the free world and you can either go on an explosion spree and have the cops chase you around or do missions for the three factions or the Agency.
The graphics are awesome. Shooting is a harder than the games predecessor Just Cause (but then again, in Just Cause Shooting is too easy).
The voice acting is off but still, come on, that doesn't effect game play that much does it?
Speaking of game play, it's pretty good when you do missions but when your not, that's when game play really sky-rockets. There are hundreds of vehicles to hijack, steal and get from the black market from sports cars to jet planes to speedboats. The funnest way to use these vehicles is to blow them up.
Making things go boom is surprisingly satisfying. There are thousands of ways to do this. You can crash a speeding car into a gas tank or fly a helicopter into a building or simply just shoot a fuel pump until it explodes.
So overall, I'd say Just Cause 2 is the best game I've played in a long time.
