Don't let the fact that the text in this tutorial is in a different language. Aside from that, everything still remains the same on what you need to do in order to unlock the Bridge Limbo achievement in Just Cause 2. All you need to do is fly an airplane under 30 unique bridges in Panau and you'll have 20 gamer points for you to take home. This may take some time to complete and it can be a bit tricky. So good luck and enjoy!
