How to use the grappling hook mod
The thing you need to use is the fishing pole. Aim in the direction which you want to go and then press the Fish button to throw the hook.
To release the hook tap on the Fish button again.
According to the Japanese source where I found this script it can be combined with the Giant Zombie Mod. This is totally optionally though.
Aim at the zombie with the fishing pole and then press Fish to throw the hook at the zombie. It really works great if you need to kill it more efficiently. Then just press Fish again to release the hook.
