Zip Line and Grapling hook

Would it be possible, or if anyone would like too, to make a zip line that you can ride down from higher to lower places on and a thrown, physics based, grapling hook that you can climb up a couple of stories with?

Sounds Good.

I was hoping for something like the ones from BF2: special forces. That would be extra cool.

I remember there used to be a grappling hook swep.

I looked but i was more like the ninja rope than an actually thrown hook.
