Note: I am making this request in the mod request boards for both fallout 3 and new vegas, both to better the odds of this mod being made, and with hope that the mod can be made compatable with both games, or have a version for each game. The thieves arsenal mod (oblivion) has vine arrows, when you shoot one at a ledge it extends a vine, or rope, that you can climb up and down. I would love to see something like this in fallout, as a grappling hook. Ether a thrown weapon that appears hook like and extends a rope off of a ledge, using the same mechanics as in the oblivion mod, or as a steam projected launcher using the rock-it launchers mesh/texture. If both models are made and used then I imagin the hand thrown hook would be lighter then the gun unit, but the gun would have better range and accuracy.
