The islands of Just Cause 3 are packed with a plethora of collectibles, including ancient tombs. Now that Just Cause 3 is free on PSPlus this month, it's time for you to smash open their stone doors and find the treasure inside! These are only found in the Insula Striate region, but there are still 23 to track down. Using the coordinates in this guide, you can find each one and pay your respects. This will push you further toward 100% completion and net you the cleverly-named Tomb Raider achievement/trophy. Things kick off on the next page!
