Helicopters can be accessed from the Helipad.
Some will have a padlock icon over them - this means that you have to meet certain requirements, for example complete a specific objective, to get access to the item!
Highlight any vehicle to see how you can unlock it. Items with a (C) icon next to them can be purchased with Far Cry Credits.
If you are having trouble locating content you should have unlocked, or have any other questions, please do not hesitate to contact us.
