The Hatchan 04 is the grappling hook that Rico uses in Just Cause Unity.
The 04 has a more stealthy design, with almost no colour. The only colour is the red on the edges of the cover and the CommLink screen. It's design is inspired from the F-117 Stealth Bomber.
The Hatchan 04 has the added functionality of being able to have a "trip mode" which solidifies the tethers so they can be crashed into. An upgrade can make these activate a GE-64 when crashed into. It also can grapple from vehicles.
