Grappling hooks
For when stairs are too boring

There's three types of grappling hooks in the game, each one supposedly of differing quality, at least judging from their prices. However, is there any -actual- difference between these three items? At least I haven't noticed any difference between the nylon Grab-It-All (or whatever it is called) and the Springfire.

Based on the model you can reach higher rooftops. So there's more rope.
