Find a military chopper | Chapter 5 - Heavy Equipment DI Riptide Guide
Last update: 11 May 2016
You have to get to Chopper Wreck which is on north from Santa Maria Mission. I strongly recommend use a boat. So take a northern exit and get on one of boats. Head north and exit the boat only when you get to the shore.
Don't bother that you can't make a straight walk to a chopper. Go east instead. Choose a path shown on the screen above, which leads northern-west.
Stay on the main path, heading northern west and then west. Soon you should see a chopper (screen). Approach him very carefully, because there are zombies nearby, which awakens when you get close. There are, among others, two Drowners which you should defeat first.
