Grappling Gun Ammo
From WikiRaider
Grappling Gun Ammo is ammunition for the Grappling Gun. They're actually little hooks that have a rope attached to them.
The ammo can be found in the level Red Alert! in Tomb Raider Chronicles. Grappling Gun Ammo is only found in sets of one, and only at a few places. But the gun has to be fired only twice, so collecting plenty of ammo isn't mandatory.
