General

Find one of the 3 escape vehicles. They will give you a list of items needed to "repair" it. Hunt the enemies for the items and return to the vehicle to repair it. Once repaired, click on the vehicle to get off the island.

Whichever vehicle you escape the island on becomes a permanent mount coupon (which IS tradable). I know the Gyrocopter has the glide function built in (jump and jump again to float), but I do not know about the boat or sub.

Thanks everyone, found my way out without having to relog
