Complete the Mission “With Friends Like These…”
So there’s a chance that you purchased Just Cause 3 with nothing more than Chaos in mind. You have no care for the story and it’s characters, nor for the innocent civilians running for their lives as you tear through the streets. Heck, General Di Ravello could stroll right past you and you probably wouldn’t even care. You just want to set the world on fire.
The developers do a good job of throwing you right into the open world. After the first mission (which begins as soon as you start the game) you’re set free to do as you please. But, you should probably do a few more missions if you want to make the best of your stay in the tropical world of Medici. Play the story until you complete the mission “With Friends Like These…” and you’ll be set for hours of mayhem. This will ensure you unlock the newer Grappling Hook (with multiple tethers), the Wing Suit, Rebel Drops, and Fast Travel. The world is absolutely huge so just the act of getting around could be a pain. Having all of the tools of the trade will make life much easier.
If you’re worried about this taking too long, don’t be. It shouldn’t take much longer than an hour to complete all of the objectives necessary.
