Take Advantage of Boom Island
Unlike most games this generation, Just Cause 3 doesn’t start installing until you actually go into the game. On PlayStation 4 it takes a solid 15+ minutes to do so (unsure about the other platforms) which can put a huge damper on your crazy fun time. Luckily, the folks over at Avalanche already thought that would be a downer and included Boom Island. This is a deserted location (as long as you don’t count animals as people) that exists solely for you to get a feel for the controls.
Use this opportunity to get a hang of the new Wing Suit that lets you majestically glide through the skies as you rain hell upon your adversaries. If it’s been a while since you’ve played the last game, you may want to brush up on your Grappling Hook/Parachute combo to rule the skies like the dangerous beast you are. Also, try out driving and basic traversal since those will play major parts in the story and challenges to come.
Boom Island is a much better alternative then going in completely blind. It’s easy to stay alive in Just Cause 3 as long as you know how to move. Don’t become another statistic on the Island of Medici.
