Unlock Grapple Hook:
When you have reached Level 2 there are territories there that you can take over. You will unlock the Grapple Hook when you have unlocked about three of them.

Bald Eagle Persuader Boat:
The Bald Eagle Persuader is a boat that looks similar to the Gungan submarine in Star Wars: Episode 1. This vehicle travels very fast on water and if you drive it in a straight line for long enough it will take off and wings will grow either side. When you land wheels will come out from underneath. This vehicle is very difficult to control and will be available about one in every ten visits to the mansion near a safehouse. This vehicle goes through cycles (sea, air, land) and if the sequence is not followed it will explode.
